Siemens Q290H QPH 2-Pole 90 Amp Circuit Breaker

The Siemens Q290H is a 2-pole, 90-amp Type QPH circuit breaker designed for 120/240V AC service. This thermally magnetic, common-trip device is intended for plug-in installation in QPH-compatible panels and load centers, offering a 22 kA interrupt rating (Icu) at 120/240V and two-pole protection. With a compact 3 x 3 x 2 inch footprint, it supports plug-in connections and, in compatible configurations, load-lug terminations for easy integration into standard Siemens panels. Catalog number Q290H identifies a 90-amp, two-pole protective device used to guard feeders and branch circuits in residential and light commercial distribution systems that rely on Siemens QP/QPH breakers, helping prevent overloads and short circuits from propagating through the electrical system. The QPH family is designed for use in Siemens panels and load centers that specify QP and QPH breakers, offering reliable overcurrent protection with a common-trip mechanism that ensures both poles operate together under fault conditions.
