There are the following differences between CB-level and PC-level ATS

2019-12-23 09:21

The CB level is composed of a circuit breaker, and the circuit breaker is responsible for breaking the arc, and requires the mechanism to trip quickly. Therefore, there may be unreliable factors such as slipping and refastening; but PC-level institutions do not have this problem. The reliability of PC products is much higher than that of CB products. Circuit breakers (MCCB) generally do not wit...
