Low-voltage circuit breaker for dual power supply (motor closing) mutual switching circuit
Source: InternetPublisher:王达业 Keywords: Low voltage circuit breaker motor power supply Updated: 2020/01/27
Dual power supply mutual transfer and self-restoration means that the load is powered by two power supplies at the same time. When one of the power supplies fails, the tie switch automatically
closes and the uninterrupted loop power supply bears the entire load. When the power supply to the power outage circuit is restored , the contact switch automatically trips and returns
to the original power supply mode. The circuit is as shown in the figure
