Siemens Q1530 – 15/30A Tandem Miniature Circuit Breaker Crafted

Expanding available circuits without adding a subpanel is achievable using the Siemens Q1530 tandem breaker. This QT series device packs independent 15A and 30A circuits into a one-inch footprint, doubling slot density. Built with a CTL rejection feature, it mounts securely into compatible Siemens EQ, PL, ES, and Ultimate load centers. It serves as a reliable replacement for the older MP1530. The 15A pole is SWD rated for lighting, and the unit includes Insta-Wire connectors.
