Siemens Q27000S01 Circuit Breaker – QP Series – 70A – 2 Pole – 120/240VAC – Plug-On – Thermal Magnetic – 120VAC Shunt Trip

The Siemens Q27000S01 is a QP Series molded case circuit breaker designed for applications requiring reliable overcurrent protection and remote disconnect capability. Rated at 70A and 120/240VAC, this 2-pole breaker combines thermal-magnetic protection with a factory-installed 120VAC shunt trip, making it ideal for residential, commercial, and light industrial electrical systems.

The breaker features Long-Time and Instantaneous (LI) trip functions to provide dependable protection against overloads and short circuits. Its plug-on design allows for quick installation in compatible Siemens load centers and panelboards, while the common-trip mechanism ensures both poles disconnect simultaneously during fault conditions.
