Siemens Q230 2 Pole 30 Amp 120/240V Circuit Breaker

Siemens Q230 is a 30 A, two-pole, plug-in molded‑case circuit breaker from the Siemens QP/MP family, designed for 120/240 V service in Siemens load centers. As a common-trip, thermal‑magnetic device, it interrupts both conductors of a 120/240 V circuit with a 10 kA interrupt rating and is UL/CSA certified for residential and light commercial use. The Q230 is a standard-size QP/MP plug-in breaker compatible with panels engineered for Type QP/MP devices, offering reliable overcurrent protection for 240 V circuits and their 120 V feeder branches. With its 2‑pole configuration, it safeguards both legs of the circuit, enabling safe operation of 240 V loads in the appropriate Siemens panel. Product documentation for US2:Q230 confirms 30 A, 2P, 120/240 V, 10K QP ratings, reinforcing its place in Siemens’ residential/multi‑family electrical protection lineup.
