Embodiments provide an Energy Reduction Maintenance Setting (ERMS) key that includes a data connector configured to communicatively couple to a data port of a target device. The ERMS key further includes an illumination device and an actuator mechanism having a base positional state and an actuated positional state. The ERMS key includes logic configured to, upon detecting the actuator mechanism has moved from the base positional state to the actuated positional state, generate and transmit a first data message to the target device through the data connector instructing the target device to enter a protected mode. The logic is further configured to, upon receiving a second data message from the target device over the data connector acknowledging that the target device has successfully entered the protected mode, cause the illumination device to illuminate.

To create a membrane keypad (1) for a protective device in the field of electrical power transmission and distribution, comprising a front decorative film (2), a shielding layer arranged behind the decorative film (2), and a printed circuit board (5) arranged behind the shielding layer, which has a central electrode (21, 22) and at least one outer electrode (19) that are at different electrical potentials, wherein a snap switch (24) can be moved from its initial position to its contact position by means of finger pressure, and the snap switch (24) in its contact position rests against the central electrode (21, 22), from which it automatically returns to its initial position when finger pressure is removed, in which it does not contact the central electrode (21, 22), which enables reliable protection against electrostatic discharges and capacitive discharge displacement and which is simultaneously simple in construction and therefore cost-effective, it is proposed thatthat the shielding layer is designed as a shielding sheet (11) which is electrically and mechanically connected to metallic conductor connecting means (14), wherein the conductor connecting means (14) are connectable to earth potential, so that a low-resistance, mechanically stable current path to earth potential is provided by means of the conductor connecting means (14).

The present invention relates to a semiconductor circuit breaker, and more particularly, to a semiconductor circuit breaker having a detachable interface module. A semiconductor circuit breaker according to an embodiment of the present invention is characterized by including: a circuit breaker main body connected to a main circuit, provided with a module accommodation portion on an external face; and an interface module provided independently of the circuit breaker main body, detachably coupled to the module accommodation portion, the circuit breaker main body including: a terminal cover rotatably coupled to a terminal portion of the circuit breaker main body; and an interlock member provided to the circuit breaker main body to restrict opening of the terminal cover or to release the restriction, the interface module including an interlock driving portion to operate the interlock member.
