Siemens Q29000S01 Circuit Breaker – QP Series – 90A – 2 Pole – 120/240VAC – Plug-On – Thermal Magnetic – 120VAC Shunt Trip

The Siemens Q29000S01 is a QP Series molded case circuit breaker designed to provide dependable overcurrent protection and remote tripping capability for residential, commercial, and light industrial electrical systems. Rated at 90A and 120/240VAC, this 2-pole breaker features a factory-installed 120VAC shunt trip, allowing remote operation for emergency shutdown and control applications.

Built with thermal-magnetic trip technology, the breaker delivers Long-Time and Instantaneous (LI) protection against overloads and short circuits. Its plug-on configuration enables quick installation in compatible Siemens load centers and panelboards, while the common-trip mechanism ensures simultaneous disconnection of both poles during fault conditions.
