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.
Automatic reset breakers don’t require you to manually reset them after they trip, so they’re good for areas where the breaker isn’t easily accessed. These breakers reset once they cool. However, they will trip repeatedly if the overcurrent condition continues.
Manual reset breakers require you to push a button after they trip.
