Siemens QF230A GFCI Ground-Fault Circuit Breaker

Siemens QF230A is a two-pole, 120/240V AC GFCI circuit breaker rated at 30 A for plug-in installation in Siemens load centers. It delivers ground-fault protection with a 5 mA trip sensitivity (Class A) and a 10 kA interrupt rating, enabling safe disconnection on leakage currents in typical residential feeders. The unit features a plug-in mount and is compatible with Siemens frame-type QFPB panels; it is part of the QF family's plug-in GFCI line. It also includes a built-in self-test and lockout function to verify operation and prevent reset after a fault, in line with UL 943 requirements for 120/240 VAC GFIs. Common applications include spa and hot tub feeders, and 120/240V circuits in kitchens and bathrooms that require GFCI protection.
