What Square D breakers meet the Class B ground fault requirements?

Are Class B ground fault breakers available from Square D?

Product Line:
Circuit Breakers

Ground Fault Protection


We don`t have any products meeting Class B requirements. CLASS B denotes a ground-fault circuit-interrupter that will trip when a fault current to ground is 20 mA or more. Our QO-EPD/EPE breakers and Molded Case Circuit Breakers with ground fault protection trip at 30 mA or more, and are not Class B.
