Holiday Sale Siemens Q21530CT2 – 15/30A Quadplex Miniature Circuit Breaker

Part of the QT series, this 15/30A quadplex breaker provides residential overload and short-circuit protection. It features inner 30A and outer 15A double-pole configurations, doubling circuit density. Designed for plug-on installation, it mounts into Siemens CTL and Murray load centers, serving as a drop-in replacement for the MP21530CT2. Both circuit pairs utilize common trip mechanisms, and the 15A poles carry an SWD rating for switching fluorescent lighting loads.
