Siemens Q23050CT2 Quad 2-Pole 30 Amp / 50 Amp Circuit Breaker

Q23050CT2 - Quad 30/50 Circuit Breaker

The Q23050CT2 quadplex circuit breaker is designed for use in compatible QT load centers that require both 30-amp and 50-amp double-pole protection in a single space-saving unit. This plug-in breaker combines two 2-pole breakers into one quadplex format, making it a practical choice when panel space is limited but additional 240V circuits are needed. Rated at 120/240VAC with a 10kA interrupting capacity, it provides proper circuit protection within its listed ratings. The common trip configuration ensures that paired poles disconnect together when necessary, supporting safe operation in multi-wire branch circuits. Built for 40°C environments and HACR applications, this breaker is intended for long-term service in properly matched electrical panels and is designed to deliver consistent form, fit, and functional compatibility.
