    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.
    Push-Button Style—Screw-On Mount

    UL 1077—They are rated UL 1077 for protection against overloads and short circuits.
    Breakthrough Current @ Voltage—Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.

    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.
    Breakthrough Current @ Voltage—Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
