Siemens QF230A Ground Fault Circuit Interrupter

Siemens QF230A is a 30 Amp, 2‑pole plug‑in ground-fault circuit interrupter (GFCI) breaker for 120/240 V electrical systems. It provides ground-fault protection by tripping when an imbalance between hot and neutral currents is detected, with a 10 kA interrupt rating and a thermal‑magnetic trip mechanism for fast, reliable response to fault or overload conditions. This model is designed for use in Siemens Type QF/QPF plug‑in panels, delivering two‑pole protection on 120/240 V circuits that require GFCI protection. The QF230A interrupts both hot legs of a 120/240 V circuit simultaneously, improving safety on multiwire branch circuits. Common applications include protected outlets and devices in areas where moisture or water exposure is a concern, such as kitchens, bathrooms, garages, basements, and outdoor circuits wired to 120/240 V. With its 30 A rating and Siemens engineering, this GFCI breaker provides a robust, reliable solution for adding ground-fault protection to dedicated circuits in residential or light commercial panels.
