Nader Circuit Breaker

Below an example MCCB brief structure, working principle, the use of circuit breakers and selection methods. Breaker consists of three basic components, i.e. the contact, release, and various interrupter system, including over-current release, voltage (undervoltage) release, heat release, shunt trip ...

High voltage circuit breaker according to generally arc extinguishing medium and the mode classification, can be divided into the oil circuit breaker less oil circuit breakers, vacuum circuit breakers, circuit breakers sulfur hexafluoride, compressed air circuit breaker, the gas circuit breaker and m...

1. The action of the air circuit breaker is an important low voltage electrical protection. It can short-circuit, overload and more undervoltage protection, can also be used to start the motor and control circuitry and other off frequently. It is characterized by the need to replace the action elemen...

Many characteristic index low voltage circuit breaker, the circuit breaker of the type [the number of poles, current type, activation mode (direct human, remote human, overcurrent, undervoltage, reverse current), the rating of the main circuit, the control loop characteristics, auxiliary circuit char...

Rated breaking current: it is characterized by the ability of the circuit breaker parameters. At rated voltage, the maximum current of the circuit breaker to ensure reliable breaking called rated breaking current, short-circuit current instant number kA rms periodic component separation unit which re...
