Best Circuit Breaker for Low Voltage

What is Electrical Circuit Breaker?

The circuit breaker is a protective device that is widely used in electrical power systems. The circuit breaker can break the circuit automatically whenever a fault occurs and can make a circuit either manually. It is a very reliable protective device that is widely used for protection purposes. It is used both low voltage and high voltage protection systems. Now we will discuss about the best circuit breaker for low voltage that is the most popular and useable for residential and official purposes.

Basically, the working principle of the circuit breaker is the same it means moving contact and fixed contact. One portion of the conductor is fixed and another portion of the conductor is moveable. Whenever faults occur the moving contact is pulled apart from the fixed contact and stops the current flow and safe the circuit or device.

What is the function of circuit breakers?

The main function of the circuit breaker is to protect the circuit from over voltage and over current. Basically, the circuit breaker consists of two parts fixed contact and moving contact. Under normal conditions, the contacts remain closed. Whenever a fault occurs then the contact becomes open and stops the current flow to the circuit.

It is noted that whenever contact is separated then the arc is stuck between them. Circuit breakers need to remove the arc as soon as possible. Basically, this arc process is seen for the high voltage circuit breakers. Alright, now we will discuss here some best low voltage circuit breakers these are widely used for low voltage protection purposes.
