Nader Circuit Breaker

The current leakage switch generally integrates leakage protection, overload protection, short circuit protection and other functions, but the leakage circuit breaker has more leakage protection function than the circuit breaker. The question of how to install correctly is in principle: Regardless of...

1. Reason analysis of air switch trip failure There are three main situations for tripping: 1.1. Where there is a problem with the line, the line is grounded, or the line meets, you can find a professional to repair it. 1.2. There are problems with the household appliances at home, so check them one ...

Vacuum circuit breakers have many advantages such as small maintenance workload, large interrupting capacity, and suitable for frequent operation. They have gradually replaced other types of switches in power systems and have been widely used. However, the operating overvoltage problem of the vacuum ...

The following points should be considered when selecting a circuit breaker. (1) The rated current and rated voltage of the circuit breaker should be greater than or equal to the rated current and rated voltage of the circuit. (2) The rated current of the trip unit of the circuit breaker should be gre...
