Match these circuit breakers to Square D breaker boxes or panel boards of the same manufacturer series. They meet UL 489 requirements for branch circuit protection. All are thermal/magnetic—breakers trip when heat is generated by sustained, low-level overload current, but will trip quickly when the magnetic field in the coil senses a high-current short circuit.

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

High-Temperature Panel-Mount AC/DC Circuit Breakers

1 Pole

2 Pole

These magnetic circuit breakers are unaffected by temperature changes so they are suitable for high-temperature environments. They trip when the magnetic field in the coil increases from current overload.

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

2-pole circuit breakers require one panel cutout for each pole.
