Siemens QF250A 2 Pole Ground Fault Circuit Breaker

Siemens QF250A is a 50-amp, two-pole ground fault circuit interrupter (GFCI) breaker for 120/240-volt split-phase circuits in Siemens plug-in panels. This plug-in unit protects both hot legs with 5 mA ground-fault sensing and interrupts fault currents up to 10,000 amps (10 kA), providing fast, reliable protection against electric shock and equipment damage. Common applications include spa or hot tub circuits and other wet-location loads such as kitchens and bathrooms where GFCI protection is required. The QF250A belongs to Siemens' QF family and uses a thermal/magnetic trip mechanism designed for dependable operation in typical residential and light commercial installations. When installed in compatible Siemens panels, it delivers dedicated branch-circuit protection for circuits demanding stringent ground-fault protection in damp environments, helping meet electrical code requirements for GFCI protection on appropriate circuits. Designed for use in Siemens plug-in panels commonly used in residential distribution systems.
