Siemens Q230GF GFCI Ground Fault Circuit Breaker

Siemens Q230GF is a 2-pole, 30-amp, 120/240-volt plug-in ground-fault circuit interrupter designed for residential use, providing ground-fault protection on typical 120/240V circuits in home electrical systems. It uses a plug-in connection and a thermal-magnetic trip mechanism compatible with Siemens QP/Q-series panels, enabling straightforward, field-replaceable installation in compatible load centers and panels used for branch-circuit protection. The Q230GF is a 2-pole, 120/240V AC breaker rated at 30A, with variants in the family that include an LED indicator and a self-test function (for example, Q230GFCSA), which helps visually confirm the device is ready to detect ground faults. Designed for residential protection, this GFCI breaker protects outlets and loads against ground faults and is suitable for circuits in bathrooms, kitchens, basements, garages, laundry rooms, and other areas where ground fault protection is helpful.
