Understanding Air Circuit Breakers

An air circuit breaker is a protective device used to control and protect electrical circuits against abnormal conditions such as short circuits and overloads. It works by interrupting the flow of electricity when it detects these hazardous situations, ensuring that both the wiring and connected devices are safeguarded.

How Air Circuit Breakers Operate

The operation of an air circuit breaker is primarily based on the principles of electromagnetism and thermal effects. When the current flowing through the circuit exceeds the predetermined threshold, the ACB activates, and its internal mechanisms take action to disconnect the electrical supply.

Key Features of Air Circuit Breakers

Air circuit breakers are designed with several features that enhance their functionality:
