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. They are rated UL1077 for protection against overloads and short circuits. 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.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.

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.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Manual reset breakers require you to push a button after they trip.
Place UL1077 rated breakers downstream from a branch circuit breaker to protect a single piece of equipment from overloads and short circuits. They are also known as supplemental protectors.
