Nader Circuit Breaker

The oil in the oil-rich circuit breaker and the oil-less circuit breaker have the same function (both transformer oil), which is mainly used for insulation and arc extinguishing. If it is mainly used for insulation and heat dissipation in the transformer. Both oil-rich and oil-less circuit breakers m...

According to the user, his house has only been renovated for two years. Recently, the air switch has been tripping. At first, it was the second trip. It was found that there was a leakage of the socket. After repairing it, it was the third trip. Push up forcibly. Sometimes it can be controlled for a ...

The air switch is a switch that trips as long as there is a short circuit, the switch forms a loop. When the line is short-circuited or severely overloaded, the short-circuit current exceeds the instantaneous tripping setting current value, and the electromagnetic tripping device generates enough suc...

See the table for the cause of the failure of the automatic air switch and the treatment method. Symptom The reason processing method manually broken path is not closed 1. No voltage or undervoltage release line ring damage. 2. Storage spring deformation, resulting in closing force is reduced. 3. Rea...

Arc extinguishing is one of the important applications of circuit breakers, because the arc will not only cause damage to the equipment circuit, but also affect personal safety. Therefore, what is necessary for arc extinguishing, there are generally four common methods of arc extinguishing, including...
