[0002] A circuit breaker lock is an electrical protection device, and more particularly, relates to a lock for preventing a circuit breaker from being misoperated. A circuit breaker is a switching device that can close, carry and disconnect current under normal circuit conditions, and can close, carry and disconnect current under abnormal circuit conditions within a specified time.
[0003] A circuit breaker generally includes a shell, components inside the shell, and a handle extending out of the shell surface at the end, wherein the handle is located in a shell groove on the shell surface. The operator can open and close the circuit breaker by moving the handle up and down, so the circuit breaker lock enters the shell groove. The circuit breaker lock is fixed relative to the handle and at the same time abuts against the shell groove, forming a handle that is not centered, ensuring that the circuit breaker state will not change, thereby preventing the circuit breaker from being operated incorrectly.
[0004] Currently, after the circuit breaker is fixed, an additional lock is required to lock the circuit breaker, which is inconvenient to operate. Utility Model Content
