    Panel-Mount Equipment Circuit Breakers

    Mount these breakers, also known as supplemental protectors, through panels downstream from a branch circuit breaker to protect a single piece of equipment. These breakers can also be used as on/off switches. All are thermal, so they use the heat generated in overcurrent situations to trip the breaker.

    Harsh-Environment Circuit Breakers

    Built to resist vibration and corrosion in harsh environments, these circuit breakers protect against overload and short circuits in low-voltage automotive and other electronic applications. All are thermal, so they use the heat generated in overcurrent situations to trip the breaker.
    Lever Manual Reset and Push-Pull Button Manual Reset—Push-pull button and lever style breakers can be used as an on/off switch.
    UL 1077—Place UL 1077-rated breakers downstream from a branch circuit breaker to protect a single piece of equipment. They are also known as supplemental protectors.
    Breakthrough Current @ Voltage—Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.

    IEC Connectors

    Pair these connectors with standard IEC power cords to bring power into or out of devices. Often used to convey power from wall outlets, there’s no need to wire your devices to an external power source. Instead, wire these connectors into your device with the terminals on the back of each connector.
    Some connectors accept a fuse (not included), which prevents short circuits and circuit overloads from damaging your device.
    Mate plugs and sockets with receptacles of the opposite gender. Plugs and sockets cannot mate with each other.
