Why thermal magnetic circuit breakers?

Siemens residential thermal magnetic circuit breakers protect your power distribution systems. We offer a range of products for electrical safety and efficiency.

Safeguard electrical circuits from overcurrents and short circuits. Our solutions prevent equipment damage, reduce electrical hazards and optimize operation by quickly interrupting fault currents.

QP breakers simplify installation with easy plug-in connections and Insta-Wire, saving you time. Duplex and QS breakers optimize panel space and streamline wiring with compact, side-wired designs.

Key benefits
