Nader Circuit Breaker

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...

The classification and main uses of circuit breakers are shown in the table Name Current the type and scope of the protection characteristics The main purpose with electric circuit breaker AC 200 ~ 4000A instantaneous delay do power The total electrical switches and branches near the switching source...

(1) Electromagnetic release When the current flowing is within the setting value, the suction force generated by the coil of the electromagnetic trip unit is not enough to attract the armature. When a short-circuit fault occurs, the short-circuit current exceeds the set value, and the attractive forc...
