Siemens Q22030CT Industrial Two Pole Circuit Breaker

Siemens Q22030CT QT triplex molded‑case circuit breaker, 120/240 VAC, rated 20–30 A with a 10 kAIC interrupt rating, is a three‑pole common‑trip unit whose outer positions are two 20 A single‑pole sections and whose center is a 30 A double‑pole section, all in a plug‑on QT configuration for Siemens load centers. It employs a thermal/magnetic trip mechanism and is built with 1/2 inch width per pole for compact installation. This triplex arrangement is designed to protect multiple 120 V and 240 V circuits within a single assembly, ensuring coordinated shutoff of all poles if an overcurrent occurs, making it suitable for use in compatible Siemens QT panels in residential or light commercial electrical systems.
