Circuit Breaker Bases & Accessories

Circuit breaker accessories can significantly enhance the functionality, safety, and efficiency of circuit breakers. These accessories are often added to the basic breaker to offer specialized features. For example, auxiliary contacts can be integrated into the circuit breaker system to provide additional control functions. An auxiliary contact is ideal for signaling the circuit's status to control panels or other equipment.

Shunt trips are another category of accessories. They are used to remotely trip the breaker from a distant location, enabling better control over electrical systems. This can be particularly beneficial in emergency situations where immediate disconnection of the circuit is necessary.

A door interlock can serve as a safety feature, ensuring that the circuit breaker panel door can't be opened unless the breaker is in the 'off' position. This helps to protect individuals from accidental contact with live parts inside the panel.
