[0019] like Figure 1-4As shown, the utility model provides a modular intelligent circuit breaker, including a cover module 10 and a body module 20, wherein the cover module 10 is detachably connected to the body module 20, and a display window 101, an operation button 102 and a quick communication module plug-in window 103 are arranged on the front of the cover module 10, wherein the quick communication module plug-in window 103 is a reserved extended communication interface, and a quick plug is arranged in the quick communication module plug-in window 103, and a separate communication module, such as a carrier communication module, etc., can be inserted when needed.

[0020] The back of the cover module 10 is provided with a first quick connector 105 and a first sealing area 106 , and the first sealing area 106 is used to separate the weak current circuit on the back of the cover module 10 from the strong current circuit of the body module 20 .

[0021] The main body module 20 is provided with a second quick connector 205 and a second sealing area 201 , and the second sealing area 201 is used to isolate the high-voltage circuit of the main body module 20 from the low-voltage circuit on the back of the cover module 10 .

[0022] A communication interface 104 is disposed on the side of the cover module 10 .

[0023] The first quick connector 105 and the second quick connector 205 are relatively pluggable and connected, and the pluggable connection is similar to the connection between a socket and a plug. The first quick connector 105 and the second quick connector 205 can complete the connection of various electrical signals between strong and weak current parts.

[0024] In this embodiment, the detachable connection between the cover module 10 and the main body module 20 may be via screws or snap-on locking, which facilitates quick disassembly, replacement and installation.

[0025] In this embodiment, the first sealing area 106 can be a sealed space formed by a detachable connection between the insulating baffle and the back of the face cover module 10, and the low-voltage circuit on the back of the face cover module 10 is placed in the sealed space, thereby separating the low-voltage circuit on the back of the face cover module 10 from the high-voltage circuit of the main body module 20.

[0026] In this embodiment, the second sealing area 201 is integrally formed with the main body module 20 , and the high-voltage circuit of the main body module 20 is located on the back of the second sealing area 201 , isolating the high-voltage circuit of the main body module from the low-voltage circuit on the back of the cover module 10 .
