Siemens Q22030CT 2 Pole 30 Amp Circuit Breaker

The Siemens Q22030CT Type QT circuit breaker is a three‑pole residential protection module that combines two 20‑amp, single‑pole circuits with one 30‑amp, two‑pole circuit in a single QT‑frame unit. It is rated for 120/240 V AC with a thermal‑magnetic trip and is UL 489 listed, offering a 10 kA short‑circuit interruption rating for typical home installations. Constructed for plug‑in mounting, each pole is 1/2 in wide, enabling compact, high‑density panel layouts in Siemens load centers that accept QT breakers. This quad/triplex style device is designed to protect mixed branch circuits within a single breaker assembly, making it suitable for multi‑circuit residential panels that require both small 20 A circuits and a higher‑current 240 V circuit in one integrated unit.
