Siemens QF220A N Ground Fault Circuit Breaker

Siemens QF220A N is a 20-amp, two-pole ground-fault circuit interrupter (GFCI) breaker engineered for 120/240-volt circuits and designed to replace or supplement standard breakers in Siemens Q-frame panels, delivering localized protection against ground faults in living spaces, workshops, and outdoor installations where moisture or water exposure is a concern. UL 943-listed and built as a plug-in GFCI with a 2-pole configuration, it provides rapid fault interruption on ground faults up to 240 VAC and carries a 10 kA short-circuit interrupt rating, making it suitable for residential load centers and applications like bathrooms, kitchens, spas, and hot tubs, where code-mandated GFCI protection is required. Variants in the QF220A family include QF220AP (packaged as P) and related neutral configurations; consult the exact packaging and panel compatibility for a correct fit, as Siemens and retailer listings often reference slightly different part designations such as QF220A, QF220AP, or QF220AN.
