When your application requires supplemental protection for control circuits and on the load side of branch circuit protectors take a look at our UL1077 miniature circuit breakers.
Molded case circuit breakers (also called MCCB's) automatically interrupt the current flowing through it when the current exceeds the trip rating of the breaker.
What is a circuit breaker used for? A circuit breaker is used to monitor and control the amount of amps being sent through the electrical wiring.
If a power surge occurs in the electrical wiring, the breaker will trip. This is when it will switch from an 'on' to an 'off' position and will shut down the electrical power leading from that breaker.
