Siemens Q230GF GFCI Ground Fault Circuit Breaker

Siemens Q230GF is a two‑pole, 30 A GFCI circuit breaker for 120/240 V circuits, designed to provide ground-fault protection for equipment on feeders that require GFCI. This plug‑in breaker carries a 10 kA interrupting rating and uses a thermal‑magnetic trip mechanism to open the circuit on ground faults or overcurrent events. It delivers 30 mA equipment‑protection GFCI sensing, making it suitable for configurations where equipment protection is specified by code. Commonly listed in retailer catalogs as US2:Q230GF, the 120/240 V, 30 A, 2‑pole GFCI is intended for plug‑in installation in compatible panels. Use it to protect circuits that must have GFCI protection, helping prevent shock hazards on feeders that serve outlets or equipment while preserving normal operation for other branch circuits.
