Technical Field

[0003] This disclosure relates to circuit breakers. Background Art

[0004] The physical volume of additional features and functions is a trade - off that circuit breaker designers often face. Conventional devices have limited features without increasing the size of the additional bar width or using additional devices that also utilize the extra space inside the panel.

[0005] Such conventional methods and systems are generally considered satisfactory for their intended purposes. However, there is still a need for improvement in the art. This disclosure provides a solution to this need. Summary of the Invention

[0006] A circuit breaker may include a housing configured to fit into a slot of a circuit board and a display configured to display information. The display may include a touch area configured to allow touch input, a variable image area configured to display trip information, diagnostic information, and / or label information, and a fixed image area configured to display fixed text that at least partially overlaps the touch area.

[0007] In some embodiments, the fixed image area may be printed text (e.g., behind a glass layer). In some embodiments, the variable image area may be a bistable display configured to maintain the displayed image without active power. In some embodiments, the bistable display may include a landscape text display such that the text is aligned with the length direction of the housing. In some embodiments, the fixed image area may include text orthogonal to the landscape text of the bistable display. In some embodiments, the fixed image area may include a "test" box that overlaps the touch area. In some embodiments, the touch area may be larger than the "test" box. In some embodiments, the touch area may overlap the bistable display and the fixed display area.

[0008] A circuit breaker may include a logic module configured to cause the display to show a label in a normal on state, test result information in a test state, and trip information in a trip state. In some embodiments, the logic module may be configured to cause a circuit information label to be displayed on the display in an off state by a mechanical or digital command.

[0009] A circuit breaker may include a mechanical handle configured to move between an ON position and an OFF position. In some embodiments, the mechanical handle further includes a trip position between the ON position and the OFF position. In some embodiments, the mechanical handle may include an "ON" label at a portion thereof visible in the ON position. The mechanical handle may be configured to move such that the "ON" label is blocked by the housing in the tripped state and the OFF position.

[0010] In some embodiments, the circuit breaker may include a trip light disposed on the housing behind the mechanical handle. The mechanical handle may be configured to hide at least a portion of the trip light in the ON position. The mechanical handle may be configured to expose the trip light in the trip position and the OFF position.

[0011] In some embodiments, a logic module may be configured to control the light state based on the state of the circuit breaker. The logic module may be configured to turn on the trip light as a solid state or blink in one or more patterns to indicate to a user a trip, test result, or other indication status, and be off in a normal ON state. In some embodiments, each of the trip, test result, or other indication status may include a unique blink pattern.

[0012] The circuit breaker may include an "OFF" label disposed on the housing behind the handle. The mechanical handle may hide the "OFF" label in the ON position and the trip position. The mechanical handle may expose the "OFF" label in the OFF position.

[0013] In some embodiments, the logic module may be configured to turn off the circuit breaker in response to a digital command (e.g., a wireless command). In such a case, the mechanical handle may not move to the OFF position, and the logic module may be configured to display a digital "OFF" label indicating that the circuit breaker is off.

[0014] According to at least one aspect of the present disclosure, a circuit breaker may include a housing configured to fit into a slot of a circuit board, a display configured to display information, a logic module, a trip light disposed on the housing, and a mechanical handle configured to move between an ON position and an OFF position. The mechanical handle may be any suitable mechanical handle disclosed herein. The circuit breaker may include any other suitable features as disclosed herein.

[0015] According to at least one aspect of the present disclosure, a circuit breaker may include a housing and a display, the housing configured to fit into a slot of a circuit board, the display configured to display information. The display may include a touch area configured to allow touch input, and a variable image area configured to display information and at least partially coincide with the touch area. The circuit breaker may further include a logic module operably connected to the touch area to receive touch input and operably connected to the variable image area to display information on the variable image area based on one or more touch inputs.

[0016] In some embodiments, the display may include a fixed image area configured to display fixed text that at least partially overlaps with the touch area. In some implementations, the fixed image area may be printed text. In some embodiments, the variable image area may be a bistable display configured to maintain the displayed image without active power. In some embodiments, the logic module may be configured to display a selected branch circuit name on the variable image area.

[0017] In some embodiments, the circuit breaker may be configured to be remotely controlled. The logic module may be configured to display a remote control (RC) status label on the variable image area and define an RC mode touch area that at least partially overlaps with the RC status label. In some implementations, the logic module may be configured to display an RC status change prompt on the variable image area if the RC mode touch area is touched such that a first touch input is received. In some embodiments, the logic module may be configured to wait for a second touch input for a set period of time after displaying the RC status change prompt. In some embodiments, if a second touch input is received before the expiration of the set period, the logic module is configured to modify the RC mode of the circuit breaker (e.g., from RC on to RC off, or from RC off to RC on) and display a new RC status label indicating the RC mode on the variable image area. In some embodiments, if the logic module does not receive a second touch input within the set period, the logic module is configured to remove the RC status change prompt, restore the variable image area to the previous display, and keep the RC mode unchanged.

[0018] The logic module may define an RC prompt touch area that at least partially coincides with the RC status change prompt to require the user to touch within the RC prompt touch area to generate a second touch input. The RC prompt touch area and the RC status change prompt may be separated from the RC status label such that the RC status label may be visible when the RC status change prompt is displayed and such that the user may touch the RC prompt touch area to change the RC mode.

[0019] In some embodiments, the circuit breaker may be configured to provide ground fault circuit interrupter (GFCI), arc fault circuit interrupter (AFCI), overload protection, short circuit protection, remote on / off control, remote trip control, and energy monitoring. In some embodiments, the logic module may be configured to provide a diagnosis of each function such that the logic module may be configured to automatically display information about the trip and the cause of the trip. In some embodiments, the logic module may be configured to display the status of the communication function, display branch circuit information, execute a test routine in response to a manually operated test button being touched, and provide a debug interface for pairing with a wireless communication system.

[0020] In some embodiments, the logic module is configured to be powered regardless of the position of a set of contacts in the circuit breaker. In some embodiments, the display is configured to present static information if the common power of the circuit breaker is lost. In some embodiments, the display may be configured to display in black and white. In some embodiments, the display may be configured to display in three or more colors. Any suitable type of display having any suitable color that can present a power-off static display is contemplated herein.

[0021] In some embodiments, the logic module may be configured to modify the display to indicate a trip state or a power loss state. In some embodiments, the logic module may be configured to flip the displayed information upside down, and / or invert the color of the displayed information to indicate the trip state and / or the power loss state.

[0022] According to at least one aspect of the present disclosure, a non-transitory computer-readable medium including computer-executable instructions is configured to cause a computer to perform a method. The method may include receiving a first touch input from a circuit breaker display associated with the state of the circuit breaker, and displaying a state change prompt on the circuit breaker display to indicate a touch area to receive a second touch input, and starting a response timer having a set period. In some embodiments, if the second touch input is received before the expiration of the set time period, the logic module is configured to modify the mode of the circuit breaker and display a new status label. In some embodiments, if the second touch input is not received within the set time period, the logic module is configured to remove the state change prompt, restore the variable image area to the previous display, and maintain the mode unchanged.

[0023] These and other features of the embodiments of the present disclosure will become more apparent to those skilled in the art from the following detailed description in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Reference will now be made to the drawings, in which like reference numerals identify similar structural features or aspects of the present subject matter. For purposes of explanation and illustration and not limitation, illustrative views of embodiments of a circuit breaker according to the present disclosure are shown in Figure 1 and are generally designated by reference numeral 100. Other embodiments and / or aspects of the present disclosure are shown in Figures 2 - 14 .

[0047] Referring to Figures 1 - 6 , the circuit breaker 100 may include a housing 101 and a display 103. The housing 101 is configured to be fitted into a slot of a circuit board (e.g., as shown in Figure 11 ), and the display 103 is configured to display information. As shown in Figure 2 and Figure 6 , the display 103 may include a touch area 105 configured to allow touch input (e.g., capacitive or resistive), a variable image area 107 configured to display trip information, status information, and / or label information, and a fixed image area 109 configured to display fixed text that at least partially overlaps with the touch area 105.

[0048] In some embodiments, the fixed image area 109 may be printed text (e.g., behind the glass layer 111). In some embodiments, the variable image area 107 may be or include a bistable display 113 configured to maintain the displayed image without active power. In some embodiments, the bistable display 113 may include a landscape text display such that the text is aligned with the length direction of the housing 101 (e.g., as shown). In some embodiments, the fixed image area 109 may include text orthogonal to the landscape text of the bistable display 113 (e.g., as shown).

[0049] In some embodiments, the fixed image area 109 may include a "test" box 115 that coincides with the touch area 105, and the "test" box 115 is configured to initiate a test function when touched. In some embodiments, the touch area 105 associated with the "test" box 115 may be larger than the "test" box 115 (e.g., to provide a wider touch area to initiate the test function). In some embodiments, the touch area 105 may coincide with the bistable display 113 and the fixed display area 109. For example, as Figure 6 shown, the bistable display 113 may be located under the capacitive film 117 that defines the touch area 105. As shown, the capacitive film 117 may be longer than the bistable display 113 and extend below or above the printed "test" box 115. The capacitive film 117 may completely surround the "test" box 115 and may extend beyond the "test" box 115, e.g., as shown. The glass layer 111 may cover all components. As shown, the capacitive film 117 may have a user interface (UI) touch space 119 such that a user can interact with the variable image area 107, and a test button area 121 that activates the test function when touched. The test button area 121 may be oversized relative to the "text" box 115 such that there are fewer user errors and / or attempts to initiate the test. The test button area 121 may extend to coincide with other printed markings (e.g., the brand marking 123).

[0050] The circuit breaker 100 may include a logic module 125 configured to cause the display 103 to display a label (e.g., a custom circuit name entered by the user) in the normal on state (e.g., as Figure 7A and 7B shown), test status information in the test state (e.g., as Figure 8A and 8B shown), and trip information in the trip state (e.g., the trip state as Figures 9A - 9C shown). In some embodiments, the logic module 125 may be configured to cause the label to be displayed on the display 103 in the off state by a mechanical or digital command (e.g., as Figures 10A - 10C shown).

[0051] The circuit breaker 100 may include a mechanical handle 127 configured to move between an ON position (e.g., as shown in Figure 7A and 7B and an OFF position (e.g., as shown in Figure 10A and 10B ). The mechanical handle 127 may be configured to mechanically open and close the contacts of the circuit breaker 100. In some embodiments, the mechanical handle 127 further includes a trip position between the ON position and the OFF position (e.g., as shown in Figures 9A - 9C ). The trip position may be a stable position between the ON position and the OFF position of the mechanical handle 127. In some embodiments, the mechanical handle 127 may include an "ON" label 129 at a portion thereof visible in the ON position. The mechanical handle 127 may be configured to move such that the "ON" label is blocked by the housing 101 in the tripped state and the OFF position (e.g., as shown in Figures 9A to 10B ).

[0052] In some embodiments, the circuit breaker 100 may include a trip light 131 disposed on the housing 101 behind the mechanical handle 127, e.g., on a shoulder 133 of the housing 101. The mechanical handle 127 may be configured to hide at least a portion of the trip light 131 in the ON position (e.g., as shown in Figure 8A and 8B ). The mechanical handle 127 may be configured to expose the trip light 131 in the trip position and the mechanical OFF position (e.g., as shown in Figures 9A to 10B ).

[0053] In some embodiments, the logic module 125 may be configured to control the light state based on the state of the circuit breaker 100. The logic module may be configured to illuminate the trip light 131 to remain steady or blink in one or more patterns to indicate to the user a trip, test status, or other condition, and turn off in the normal ON state. In some embodiments, each of the trip, test status, or other conditions may include a unique blink pattern. For example, a test failure may be indicated by a steady illumination of the trip light 131. A ground fault trip may be indicated by a blinking illumination of the trip light 131 having a first blink rate and / or a first blink pattern. Different electrical fault types may be indicated by a blinking illumination of the trip light 131 having a second blink rate and / or a second blink pattern. Any suitable blink pattern and / or rate for indicating any number of electrical fault types are contemplated herein.

[0054] The circuit breaker 100 may include an "OFF" label 135, e.g., as shown in Figure 10A and 10CAs shown, it is provided on the housing 101 behind the handle 127. The mechanical handle 127 can be in the on position (e.g., as shown in Figure 8A and 8B ), and in the trip position (e.g., as shown in Figures 9A - 9C ), to hide the "OFF" label 135. The mechanical handle 127 can expose the "OFF" label in the mechanical off position, e.g., as shown in Figure 10A and 10B .

[0055] In some embodiments, the logic module 125 can be configured to turn off the circuit breaker 100 in response to a digital command (e.g., a wireless command). The circuit breaker 100 can include a motor (not shown), which is configured to actuate a contactor between the on state and the off state regardless of the handle position. The logic module 125 can be configured to operate the motor in response to a command and / or according to logic. For example, the logic module 125 can be configured to wirelessly communicate (e.g., via the Internet, via a direct connection, and / or via a local wireless system) with another device (e.g., a smart device, a computer) to allow control of the circuit breaker 100 using another device. In such a case, the mechanical handle 127 may not be moved to the off position as shown in Figure 10C , and the logic module 125 can be configured to display a digital "OFF" label 137 indicating that the circuit breaker 100 is off.

[0056] Figure 11 Shows a part of the circuit breaker panel 1100, which has multiple embodiments of Figure 1 mounted therein. The panel 1100 can include any suitable number of circuit breakers 100 and / or any other suitable type of circuit breaker disclosed herein.

[0057] According to at least one aspect of the present disclosure, a circuit breaker (e.g., circuit breaker 100) can include a housing 101 configured to fit into a slot of a circuit board 1100, a display configured to display information, a logic module 125, a trip light 131 provided on the housing 101, and a mechanical handle 127 configured to move between an on position and an off position. The mechanical handle 127 can be any suitable mechanical handle 127 disclosed herein. The logic module 125 can be any suitable module 125 disclosed herein. The circuit breaker 100 can include any other suitable features as disclosed herein.

[0058] Embodiments may include a trip light 131 that moves from below the handle 127 to above the handle 127, and the trip light 131 is hidden by the handle in the on state. For example, the light may flash under certain trip conditions (e.g., a ground fault). The light pattern may be a reliable and / or redundant way to determine the type of electrical fault (e.g., in cases where the display 103 cannot otherwise show the reason for the trip). Any suitable light pattern is contemplated herein. The trip light may include, for example, a light tube 131a that diffuses the light from the LED 131b.

[0059] Embodiments may include a handle that rotates upward to cover the trip when switched on and may have a mechanical indicator for "on" that is only visible when rotated upward. In some embodiments, the handle may be long enough to cover a portion of the trip light, rather than the entire trip light. The handle may be sized to mostly or completely cover the word "trip" on the trip light.

[0060] Embodiments may include a display having a capacitive touch zone behind the physical test and logo symbols. The touch zone may include an oversized test button area that does not match the word "test" to provide a wider activation area. Some text (e.g., "test" and the logo) may be physically printed and behind the glass. The logic module may control what is displayed on the variable image area and may be configured to process inputs from the capacitive touch zone to allow the user to interact with the device and / or initiate a test function. For example, if the test button is touched / pressed, the logic module may initiate a self-test and trip if the test result is positive. In some embodiments, if no problem is detected, the logic module may output an affirmative indication (e.g., the word "pass") to the display. In this regard, the display may include a dynamic screen with real-time feedback.

[0061] Some embodiments may include a miniature circuit breaker with advanced protection, remote control, communication, and touch display having a single-pole width format and / or other dimensions. The physical volume of additional features and functions is a trade-off that circuit breaker designers often face. So far, no other device has been able to achieve each feature listed in the summary of the invention without increasing the size of the additional pole width or also using additional space inside the panel for additional devices.

[0062] Embodiments may allow for all features to be provided while using no more circuit space within an electrical panel than a conventional thermal magnetic circuit breaker that does not have advanced protection, remote control, communication, or a display that can provide rich information. Conventional advanced function circuit breakers add pole space for increased volume to accommodate communication and UI indicator components. Other solutions on the market today can only use external control devices to implement all of the features disclosed herein. This increases cost, increases the space used inside the panel, and increases system complexity.

[0063] Embodiments may include an advanced protection circuit breaker having multiple functions (e.g., arc fault, ground fault, thermal fault, and magnetic fault). And a compact energy storage motor mechanism may be added to open and close electrical contacts via remote control, mechanical means to link the remote control mechanism to a conventional main electrical contact, a motor control circuit integrated with the protection, communication, and monitoring circuits in the circuit breaker, a radio transmitter and receiver communication system to connect to remote control devices, an innovative bistable display (electronic ink) that can display rich variable dynamic information to a local user about the circuit breaker status, electrical fault parameters, QR codes, circuit identifiers, but also has a permanent marking for UL standard test compliance, a display having two touch function areas (one for initiating a UL standard user test check and two for a user to interact with the display to obtain additional information and / or digitally change the status of the circuit breaker to open or closed), and software and firmware to perform all functions of the other elements. Embodiments have components that implement functions with a minimum number of parts and a minimum footprint, and all components can work in concert to operate the circuit breaker, interact with externally connected systems, interface with local users, and meet applicable codes and standards.

[0064] According to at least one aspect of the present disclosure, with additional reference to Figures 12 - 14 , the circuit breakers 100, 1200 may include housings 101, 1201 configured to fit within slots of a circuit board 1100 (e.g., the circuit breaker 100 in a single-pole slot, the circuit breaker 1200 in a double-pole slot, or any other suitable configuration for any suitable number of poles). The circuit breakers 100, 1200 may include a display 103 configured to display information. The circuit breaker 1200 may be similar to the circuit breaker 100 in a double-pole form. The circuit breaker 1200 may have any suitable additional functions.

[0065] The display 103 may include a touch area 105 configured to allow touch input, and a variable image area 107 configured to display information and at least partially (e.g., completely) coincide with the touch area 105. The circuit breakers 100, 1200 may further include a logic module 125 operably connected to the touch area 105 to receive touch input and operably connected to the variable image area 107 to display information on the variable image area 107 based on one or more touch inputs.

[0066] In some embodiments, the display 103 may include a fixed image area 109 configured to display fixed text (e.g., as described above) that at least partially coincides with the touch area 105. In some implementations, the fixed image area may be printed text (e.g., as described above). In some embodiments, the variable image area 107 may be a bistable display, such as similar to the electronic ink technology described above, configured to maintain the displayed image without active power. In some embodiments, the logic module 125 may be configured to display the selected branch circuit name (e.g., as shown: "Water Heater") on the variable image area 107.

[0067] In some embodiments, the circuit breakers 100, 1200 may be configured to be remotely controlled (e.g., the logic module 125 may be configured to wirelessly communicate with another device and / or network). The logic module 125 may be configured to display a remote control (RC) status label 1301 on the variable image area 107, e.g., as Figure 13A shown. The logic module 125 may further define an RC mode touch area that at least partially coincides with the RC status label 1301 (e.g., the area around the text, e.g., up to and / or including the underlining shown). Any other suitable status for the display and associated defined touch areas is contemplated herein. Any suitable number of statuses is contemplated herein, however, the amount of statuses displayed may be limited by the size of the display and / or the desired minimum size of the touch area / text while still allowing the display of the branch circuit name text. In some embodiments, no status may be initially displayed and there may be a menu button that causes an option menu for changing one or more states of the circuit breaker to be displayed. Any logic for navigating to a state change on the display is contemplated herein.

[0068] In some implementations, as Figure 13B shown, the logic module 125 may be configured to display an RC status change prompt 1303 on the variable image area 107 if the RC mode touch area is touched such that a first touch input is received. Also refer to Figure 14, in some embodiments, the logic module 125 may be configured to wait for a second touch input for a set period of time after displaying an RC status change prompt. In some embodiments, if a second touch input is received before the expiration of the set period of time, the logic module 125 may be configured to modify the RC mode of the circuit breakers 100, 1200 (e.g., from RC on to RC off, or from RC off to RC on) and display a new RC status label indicating the RC mode on the variable image area 107. In some embodiments, if the logic module 125 does not receive a second touch input within the set period of time, the logic module 125 may be configured to remove the RC status change prompt 1303, restore the variable image area 107 to the previous display, and keep the RC mode unchanged. This process and / or logic may be used for any suitable status change accessible via the display 103.

[0069] The logic module 125 may define an RC prompt touch area that is at least partially (exactly) consistent with the RC status change prompt 1303, to require the user to touch within the RC prompt touch area (e.g., within the RC status change prompt 1303) to generate a second touch input (e.g., the logic module 125 accepts the second touch input as confirmation of changing the status). The RC prompt touch area and the RC status change prompt 1303 may be separated from the RC status label 1301 (e.g., as shown in the figure), such that the RC status label 1301 may be visible when the RC status change prompt 1303 is displayed, and such that the user may or must touch the RC prompt touch area to change the RC mode.

[0070] In some embodiments, the circuit breaker may be configured to provide ground fault circuit interrupter (GFCI), arc fault circuit interrupter (AFCI), overload protection, short circuit protection, remote on / off control, remote trip control, and energy monitoring. In some embodiments, the logic module 125 may be configured to provide a diagnosis for each function, such that the logic module 125 may be configured to automatically display information about tripping and the reasons for tripping. In some embodiments, the logic module 125 may be configured to display the status of the communication function (e.g., the wireless symbol shown when wirelessly connected), display branch circuit information (e.g., the name of the branch), execute a test routine in response to a manually operated test button being touched (e.g., as described above), and provide a debug interface for pairing with a wireless communication system (e.g., one or more prompts and / or menus that allow the user to configure wireless settings and / or put the device in pairing mode).

[0071] In some embodiments, the logic module 125 is configured to be powered regardless of the position of the contactor in the circuit breakers 100, 1200. In this regard, as long as there is utility power, the logic module 125 and the display 103 can be powered. In some embodiments, the display 103 is configured to present static information if the utility power of the circuit breakers 100, 1200 is lost. In some embodiments, the display 103 can be configured to display in black and white, for example, as shown. In some embodiments, the display 103 can be configured to display in three or more colors. Any suitable type of display (e.g., bistable, multistable) having any suitable color that can present a power-off static display is contemplated herein.

[0072] In some embodiments, the logic module 125 can be configured to modify the display 103 to indicate a trip / fault state or a power loss state. In some embodiments, the logic module 125 can be configured to flip the displayed information up and down, and / or invert the color of the displayed information to indicate a trip / fault state and / or a power loss state. For example, if utility power is lost, the logic module 125 can invert the display color as a final update before shutting off. Any suitable visual change in response to any suitable fault or other problem is contemplated herein.

[0073] In some embodiments, the logic module 125 can be configured such that the displayed image or text can be rotated to match the orientation of the circuit breaker. For example, if the circuit breaker is installed on the right side of the panel, the text or image can be inverted relative to the circuit breaker installed on the left side of the panel such that the displayed image or text will be right side up. In some embodiments, the logic module 125 can use data from an accelerometer to determine the orientation of the circuit breaker after installation. In some embodiments, the orientation of the text can be manually set by the user using one or more controls (e.g., buttons, digital cues, menus, etc.).

[0074] According to at least one aspect of the present disclosure, a non-transitory computer-readable medium includes computer-executable instructions configured to cause a computer to perform a method. The method can include receiving a first touch input from a circuit breaker display associated with a state of a circuit breaker, and displaying a state change prompt on the circuit breaker display to indicate a touch area to receive a second touch input, and starting a response timer having a set period. In some embodiments, if a second touch input is received before the expiration of the set time period, the logic module is configured to modify the mode of the circuit breaker and display a new state label indicating the new mode. In some embodiments, if a second touch input is not received within the set time period, the logic module is configured to remove the state change prompt, restore the variable image area to a previous display, and maintain the mode unchanged.

[0075] Embodiments may include an advanced function circuit breaker having a touch screen display. Embodiments may provide any and / or all of arc fault protection (AFCI), ground fault protection (GFCI), overload protection, short circuit protection, remote on / off control, remote trip, and / or energy monitoring. Embodiments may include a touch screen display through which local control of remote on / off functions, the status of remote on / off functions, the diagnosis and status of advanced protection functions, reporting of trip events, the status of communication functions, branch circuit information, a supervised test button for manual operation, and a debugging interface (e.g., for pairing in a zigbee system) can be performed.

[0076] Embodiments may include any suitable touch buttons, e.g., a touch screen display having multiple touch buttons, allowing a user to interface with the advanced circuit breaker. The touch buttons may be touch sensitive without using dedicated mechanical contacts. The touch buttons may use capacitive or resistive touch sensitive technology. The touch button interface may also implement supervised testing of manual operations. The touch button interface may also enable commissioning the advanced circuit breaker into a wireless communication system.

[0077] Embodiments may include a display that allows presentation of advanced function circuit breaker information to a user. For example, the display may provide branch circuit information communication status, on / off control status, trip events, and / or advanced function diagnosis. The display may have the ability to continue displaying information after a trip event or when the circuit breaker is off. The display may have the ability to continue to be read after power is completely removed from the line side of the circuit breaker (e.g., using, e.g., electronic ink technology). The display may be any combination of black and white or color. The display may include permanent markings located adjacent to a variable image area. Some markings may be longitudinally oriented and some may be transversely oriented (e.g., as shown).

[0078] Embodiments may include a touch screen display having an indication of the status of a remote on / off function. The touch screen may have the ability to accept a touch from a user to enter a mode that allows changing the status of the remote on / off function. In certain embodiments, the display may have, for example, a second soft touch button that accepts touch input to change the RC status. For example, in certain embodiments, pressing a specific button to change the status allows the on / off status to change. Any combination of display screens and soft buttons for accomplishing the same tasks as those accomplished above is contemplated herein. For example, embodiments may allow on / off control to be turned on from an off state and turned off from an on state.

[0079] Embodiments may include a touch-sensitive button that serves as a manually operated supervisory test button for an advanced function circuit breaker. For example, the touch-sensitive button may use capacitive touch sensor technology. The capacitive touch sensor may be integrated into a user interface that includes a display. The test button portion of the user interface has a permanently printed area labeled "Test" that is not part of the variable display. The capacitive touch test button may be connected to a circuit inside the advanced function circuit breaker to provide a signal for initiating the supervisory test function of the manual operation when the test area is touched.

[0080] Embodiments may allow for the display of variable circuit information (e.g., self-labeling, custom labeling) on the circuit breaker. This can obviate the need for panel labels. Accordingly, embodiments may include an advanced function circuit breaker having an integrated display for displaying labels of connected branch circuits. The display may use bistable technology, which has the ability to continue presenting static branch circuit information (e.g., labels) in the event of a power outage on the line side of the circuit breaker. Embodiments may also change how the labels are displayed (e.g., color appearance, orientation, etc.) when there is a reported event (e.g., trip, power outage, test status, etc.). For example, branch circuit labels may be input during system commissioning through an application associated with the device (e.g., on a connected smart device). Any other suitable method of modifying branch circuit labels is contemplated herein.
