Siemens Q230GF GFCI Ground Fault Circuit Breaker

Siemens Q230GF is a 30-amp, 2-pole ground-fault circuit interrupter (GFCI) breaker designed for 120/240-volt circuits, part of the Siemens Q-series and engineered for plug-in installation in compatible Siemens panels. As a GFCI device, it detects imbalance between the circuit conductors and neutral and interrupts power on a ground fault using a thermal-magnetic trip mechanism to deliver rapid protection on multi-wire branch circuits. This 2-pole configuration safeguards both live conductors on the circuit, enabling GFCI protection on circuits where code requires rapid disconnection in the event of a ground fault. The Q230GF is listed within Siemens’ Q-series lineup for straightforward replacement of standard two-pole breakers in compatible panels, providing reliable ground-fault protection without altering the overall panel architecture.
