Circuit Trips

Circuit trips react to ground faults, short circuits or thermal overload in circuit breakers. A circuit trip opens the circuit in the event of a faulty condition. The trip becomes activated when it senses heat from an overload or high current from a short circuit.


What are the different types of circuit trips?


There are two types of circuit trips: electromechanical and electronic. An electromechanical circuit trip has two moving parts that work together to determine when to open the circuit. The two parts are a current-sensitive device and a thermal-sensitive device. An electric circuit trip is less mechanical as it's a programmable device. It measures and times the current flowing through the circuit breaker, electronically delivering a trip signal when it's needed.


How to choose the right circuit trips


Choosing the right circuit trips depends on the circuit or device you're using it for. There are various features that should be considered when selecting the right circuit trips, such as rated-control voltage and the current rating.
