Siemens Q2110H 2 Pole 110 Amp Type QP Circuit Breaker

Siemens Q2110H is a 2-pole molded-case circuit breaker rated for 120/240 VAC and 110 A, part of the Type QP family with a QPH frame, designed for plug-in installation in Siemens load centers. It uses a thermal-magnetic trip to provide reliable overload and short-circuit protection, delivering a 22 kA interrupt rating at 240 VAC for circuits with higher fault currents. The plug-in design supports quick replacement, it features common-trip operation so both poles trip together on a fault, and some configurations offer a load-lug terminal option to simplify feeder connections. This two-pole device is commonly used to protect 240‑V branch circuits in residential distribution panels and light commercial installations, and it maintains the compact form factor and compatibility of the QP/QPH family. When replacing older devices, ensure you verify the correct frame size and panel compatibility to maintain proper protection and code compliance.
