Product Description

AC Circuit Breaker Manufacturer

AC circuit breaker is an essential safety device used in electrical systems to protect electrical circuits from excessive current flow due to an overload or a short circuit.  AC Circuit breakers are typically used in residential, commercial, and industrial applications to maintain the safety and functionality of electrical systems.

The main components of an AC circuit breaker are:

Contacts: These are the conductive parts that allow the flow of current when the circuit breaker is closed (ON position) and interrupt the current flow when the circuit breaker is open (OFF position).

Bimetallic strip: This component is made from two different metals bonded together. The strip bends when heated due to the difference in thermal expansion coefficients of the metals. In the event of an overload, the heat generated by the excessive current causes the bimetallic strip to bend, triggering the circuit breaker to trip and interrupt the current flow.
