Siemens QF120AN GFCI Circuit Breaker Ground Fault

Siemens QF120AN is a 20-amp, 120-volt, 1-pole GFCI circuit breaker with plug-on neutral, designed to provide Class A (5 mA) ground-fault protection for personnel on residential and light commercial circuits without the need for a neutral pigtail. It carries a 10 kAIC interrupt rating at 120 V, allowing it to safely interrupt typical fault currents, and the plug-on neutral design eliminates the need for a separate neutral pigtail in compatible Siemens load centers. The QF120AN is listed for Siemens Type EQ, EQL, and SEQ load centers, ensuring compatibility with Siemens' standard panel platforms and enabling straightforward replacement in existing installations while maintaining system-wide coordination with other Siemens breakers. As part of the Siemens QF family, this 1-pole, 120 VAC device guards a single branch circuit against ground faults, delivering reliable protection for outlets and connected equipment while preserving the familiar form factor and mounting orientation of Siemens low-voltage breakers. Typical procurement sources for this model include Siemens-authorized retailers and distributors, reflecting its status as a common, code-compliant option for adding GFCI protection in residential panels.
