Different Types of Circuit Breakers

A circuit breaker consists of both fixed and moving contacts. When the circuit is closed, the contacts touch each other and carry the current under normal conditions. In this state, the electrodes, which are the current carrying contacts, interact under the pressure of the spring. In normal conditions, the circuit breaker’s arms can be either closed or opened for switching regulator and maintenance of the system. To open the circuit breaker, just apply pressure to the trigger. This allows it to easily deal with things such as overloads and short circuits.

When the circuit detects a fault, previously stored mechanical energy, or even the higher current itself, is used to separate the contacts. When the fault is cleared, the contacts can be closed again to restore power to the circuit.

There are many different types of circuit breakers. This includes, but is not limited to, the following: oil circuit breaker, minimum oil circuit breaker, air blast circuit breaker, Sulphur hexafluoride circuit breaker, vacuum circuit breaker, and air break circuit breaker. Most often, circuit breakers are arranged based on rated current voltages. Circuit breakers below 1000 volts are identified as the low voltage circuit breakers, and circuit breakers above 1000 volts are identified as high voltage circuit breakers.
