Siemens Q22050CT2 Quadplex Circuit Breaker

Overview

The Siemens Q22050CT2 is a 240V AC, 50A/20A quadplex circuit breaker designed for residential load centers. It combines two 2-pole breakers—one 50A and one 20A—into a single breaker unit, allowing for efficient use of panel space. This configuration is ideal for applications where multiple circuits are needed but panel space is limited.
