Electromagnetic auxiliary circuit breaker

The invention discloses an electromagnetic auxiliary circuit breaker and relates to the electrical product technology field, and the electromagnetic auxiliary circuit breaker comprises a circuit breaker main body, a closing mechanism and an electromagnetic auxiliary device, the circuit breaker main body is used for realizing the on/off of the current in an accessed circuit, and the closing mechanism is used for realizing the on/off of the circuit breaker main body when the small current flows through the circuit breaker main body. And the electromagnetic auxiliary device is used for assisting the closing mechanism to realize opening/closing of the circuit breaker main body when large current flows through the circuit breaker main body. In practical application, the electromagnetic auxiliary circuit breaker is also suitable for a circuit through which small current or large current flows so as to realize reliable the on/off of the current in the accessed circuit. 本发明公开了一种电磁辅助断路器，涉及电气产品的技术领域，包括断路器主体、闭合机构及电磁辅助装置
