Siemens QF260 Circuit Breaker

Siemens QF260A is a 60-amp, two-pole, plug-in Ground Fault Circuit Interrupter (GFCI) molded‑case circuit breaker for 120/240‑V systems. It belongs to the Siemens Q-Series family and uses a thermal-magnetic trip mechanism to provide both overcurrent and ground-fault protection. Rated for up to 10,000 A interrupting capacity at 240 V, it disconnects quickly on faults to help prevent electrical shock and equipment damage. As a GFCI breaker, it monitors the imbalance between hot and neutral conductors and trips on a detected ground fault, typically at 5 mA, giving protection in wet or damp locations and on circuits feeding outlets in kitchens, bathrooms, laundry rooms, and garages. The QF260A is designed for plug‑in installation in compatible Siemens load centers and panels, offering convenient replacement without significant wiring changes. It is commonly cataloged as 60 A, 2-pole, 120/240 V, 10 kAIC, and is available from Siemens and distributors such as Crescent Electric, SupplyHouse, and Lowes, with variations in the catalog for plug-on neutral configurations in related models. This model provides integrated overcurrent and ground-fault protection in a compact molded‑case form factor, making it suitable for residential protective device panels that require GFCI protection on 120/240 V circuits.
