Description

Technical Field

[0001] The utility model relates to the field of circuit breakers, in particular to a novel low-voltage circuit breaker. Background Art

[0002] A circuit breaker is a switching device that can close, carry and interrupt current under normal circuit conditions and can close, carry and interrupt current under abnormal circuit conditions within a specified time. It has overload, short circuit and undervoltage protection functions to protect lines and power equipment from damage.

[0003] The circuit breaker in the related art usually includes a circuit breaker body, on which a switch key is rotatably connected. When the switch key is pushed upward, the circuit breaker connects the circuit. When the circuit breaker trips, the switch key automatically rotates downward, thereby cutting off the circuit to protect the line and power equipment.

[0004] Currently, circuit breakers are often installed in an integrated manner to facilitate management, with multiple breakers installed side by side in an electrical cabinet. However, since the circuit breakers are nearly identical in appearance, it can be difficult to distinguish between specific breakers when a user wishes to shut down a particular one, making it easy to accidentally shut down a breaker. This compromises usability and requires improvement. Utility Model Content
