    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.

    Blade-Style Circuit Breakers

    Protect against overload and short circuits in low-voltage automotive and other electronic applications. These circuit breakers can replace type ATC, AF, ATO, and 257 blade-style fuses. They are thermal, so they trip when heat is generated by overload current.
