    Your circuit breaker accessories are as important as your circuit breakers.

    They say that the devil’s in the details, and your circuit breakers and your electrical system are no different. Your electrical system is only as good as the sum of its parts, so you better make sure your circuit breaker accessories are up to scratch. Bay Power carries many circuit breaker accessories including undervoltage releases, shunt trips, rating plugs, trip units, breaker handle ties and lugs, all available in a variety of voltage and amp ratings to meet your individual needs.

    What do circuit breaker accessories do?

    If you’re wondering, “Why do my circuit breakers trip?” you might need to bolster your circuit breakers with a few of the following accessories:

    • Undervoltage releases, or UVR’s for short, protects the circuit breaker by tripping it when the voltage falls between a certain percentage range.
    • A shunt trip is another optional protective device that can mechanically trip the circuit breaker since it is not powered by the circuit breaker itself.
    • A trip unit is the mechanism inside a circuit breaker that opens the circuit in the event of an overload or ground fault. In some circuit breakers, this can be replaced.
    • Rating plugs designate the amperages inside the trip unit in which it is installed. Each trip unit is only intended for use with a specific trip unit.
