Circuit Breakers

Circuit breakers for HVAC equipment and residential load centers, from 3 amp control-circuit breakers up to 60 amp two-pole. Ratings in this range are 3, 5, 15, 20, 25, 30, 35, 40, 45, 50 and 60 amp, in 1-pole and 2-pole, at 24, 120, 120/240, 208-230, 240 and 250 VAC.

Breaker lines are not interchangeable across panel brands. Match the panel and its breaker family first — QO and Homeline are different Square D lines and are not substitutes for each other — then the amperage and pole count. Both Square D lines are here, alongside Siemens Q and Siemens-Furnas, Eaton BR, Cutler-Hammer CH, and equipment-specific breakers from Bard, Nortek, DiversiTech, MARS, Supco and Zebra.
