30 amp double pole ac circuit breaker Composition
A common small circuit breaker uses mechanical methods to separate its moving and fixed contacts when opening the circuit, while when closing the circuit, it uses opposite mechanical movements to close the moving and fixed contacts. When interrupting and connecting the load circuit during operation, an arc will be generated between the contacts. The arc generated during the breaking process is more severe than during the closing process. When the current to be disconnected is large, especially in the case of a short circuit, the arc will be large, so disconnecting the circuit is usually very difficult.
