Siemens Q220 QP Circuit Breaker Two Pole 20A 120 240V

The Siemens Q220 is a two-pole, 20-amp Type QP plug-in circuit breaker rated for 120/240 V AC, designed to protect residential and light-commercial branch circuits in Siemens QP-compatible load centers and panels, making it straightforward to upgrade or replace existing breakers. It provides thermal-magnetic trip protection with a 10,000 AIC (10 kA) interrupting rating, enabling prompt disconnection on overload or fault currents and aligning with common residential protection standards. The Q220 is interchangeable with Siemens Type QP panels and load centers, allowing seamless replacement or expansion in existing Siemens systems, and its plug-in design enables straightforward installation in compatible Siemens panels. Typical applications include safeguarding 120/240 V branch circuits in homes and small businesses, such as circuits for lighting, receptacles, and appliances, within Siemens residential load centers, with a 2-pole configuration that provides coordinated protection for multiwire branch circuits.
