Nader Circuit Breaker

Why should the circuit breaker be derated and used? First of all, when the operating environment temperature of the circuit breaker is greater than the specified value, it needs to be derated. It is generally specified as 40C (the temperature exceeds 65C during motor protection). Under what circumsta...

How to wire the circuit breakers neutral wire? The circuit breakers used in the family can be divided into five types: 1P circuit breaker, 1P+N circuit breaker, 2P circuit breaker, 1P leakage circuit breaker and 2P leakage circuit breaker. When wiring, the 1P circuit breaker does not need to distingu...

The direction of incoming and outgoing wires of low-voltage circuit breakers cannot be reversed because the operating mechanism on the moving contact side and the static contact side of the circuit breaker has different dielectric properties, and the arc roots on the moving and static terminals of th...

The function of the circuit breaker in the circuit is to automatically break the circuit when overload, short circuit and voltage loss exceeding the allowable limit occur, and to make and break the circuit infrequently under normal conditions. The function of the wire should be able to carry the need...

The air switch has a trip accident, and the attempt to close cannot be successful. In addition to troubleshooting its own fault, it is generally because the line fault has not been eliminated. You can try the following methods to eliminate the fault: 1. Tripping failures are generally divided into se...
