Siemens Q24040CT2 – 40A Quadplex Miniature Circuit Breaker Brand New

Built to optimize residential panel space, the Siemens Q24040 is a quadplex breaker that provides two independent 40A circuits. By condensing four poles of protection into a two-pole footprint, it allows for system expansion without requiring a larger enclosure upgrade. This plug-on miniature breaker mounts into Siemens EQ, Ultimate, PL, and ES series load centers. It is replaced by the newer Q24040CT2 model. Rated for 10kA at 120/240VAC, it includes common trip functionality for both pairs.
