Nader Circuit Breaker

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...

When the circuit breaker cuts and closes, an arc is generated between the moving and static contacts. The arc temperature is very high. If it cannot be extinguished within a limited range as soon as possible, nearby parts will be damaged. For high voltage arcs, due to the high recovery voltage , It i...

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 ...
