Certified Siemens QF250A – 50A GFCI Miniature Circuit Breaker

Built for modern safety standards, the Siemens QF250A is a 50A, two-pole GFCI breaker featuring an integrated self-test function. This Class A 5mA device automatically verifies its ground-fault circuitry, ensuring reliable protection for wet locations. Designed as a direct upgrade, this plug-on breaker replaces the legacy QF250 and installs into Siemens EQ, ES, PL, and Ultimate load centers. With a 10 kAIC rating at 120/240V, it provides robust thermal-magnetic overcurrent protection.
