Nader Circuit Breaker

The circuit breaker in the open position is the time from the moment when the closing circuit is energized to the moment when all pole contacts are in contact. Unless otherwise stated, the closing time refers to the instant until the main contacts are in contact. The closing time refers to the time i...

Vacuum circuit breakers use vacuum as the arc extinguishing and insulating medium. The parts are sealed in a shell made of insulating glass and other materials, and the sealing of the movable contact rod and the movable contact is realized by a metal bellows. The empty circuit breaker has the followi...

The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts ...

There are many types of high-voltage circuit breakers, and they can generally be classified according to the following methods: according to the installation location of the circuit breaker, they can be divided into indoor and outdoor types; according to the arc extinguishing principle or arc extingu...

1. Rated voltage Rated voltage refers to the voltage level that the high-voltage circuit breaker can withstand during normal operation, and it determines the insulation level of the circuit breaker. The rated voltage (UN) refers to its line voltage. The rated voltage levels of commonly used circuit b...
