Nader Circuit Breaker

The main varieties of circuit breakers are: molded case circuit breakers, leakage circuit breakers, miniature circuit breakers, high breaking miniature circuit breakers, high breaking miniature earth leakage circuit breakers, and intelligent universal circuit breakers. The molded case circuit breaker...

When choosing a circuit breaker to protect a motor, two characteristics of the motor should be noted, one is that it has a certain overload capacity, and the other is that its starting current is usually several to ten times the rated current. Therefore, circuit breakers for motor protection are divi...

Low-voltage circuit breakers were once called automatic switching, which refers to the on-off operation and protection of distribution circuits, motors or other electrical equipment according to prescribed conditions, that is, automatic switching when there is an overload, short circuit or undervolta...

Circuit breakers have short-circuit tripping and thermal tripping modes. Short-circuit tripping means that the huge current generated by a short-circuit fault in the circuit causes the short-circuit release to act quickly to disconnect the circuit to achieve the purpose of protection. Thermal trip me...

How to choose the size of the switch (breaker, etc.)? Generally, how much is more appropriate than the rated current? Generally choose 1.5 times to 2 times the load, the load capacity is large, the starting current is large and the starting current is large, and the starting current is selected 1.5 t...
