Siemens QE120 Equipment Ground Fault Protection Circuit Breaker

Siemens QE120 is a 20 A, 1-pole GFCI circuit breaker in the QE family, designed for 120 V residential distribution panels. It provides ground-fault protection and overcurrent protection with a 30 mA trip threshold and a 10 kA interrupting rating, making it suitable for branch circuits that require safeguards against ground faults. This plug-in device is built for Siemens QE-series equipment-protection panels, offering a standard 120 V AC operation and a 20-ampere rating. Typical uses include protecting circuits in areas where ground-fault protection is required by electrical code, such as kitchens, bathrooms, or utility spaces that rely on GFCI protection.
