Siemens Q230H U 2 Pole 30 Amp 240 Volt Circuit Breaker

Siemens Q230H-U is a two-pole, 30-amp, 240-volt plug‑in molded‑case circuit breaker from the Siemens Q‑series. It employs a thermal‑magnetic, common‑trip mechanism with a 22,000 AIC (22 kA) interrupt rating at 240V, designed to protect a 30A, 240V branch circuit in residential load centers and other QP/QPH panels. This 2P unit is intended for plug‑in mounting in Siemens QP/QPH panels and accepts standard Q‑series accessories, with a 120/240V AC rating appropriate for typical split‑phase residential wiring. In normal operation it disconnects both hot conductors simultaneously on fault, helping maintain safety and code compliance for 240V feeders and branch circuits in homes and light commercial installations. Suitable for retrofit or new installations in compatible Siemens panels, the Q230H-U is part of the legacy Q series commonly used where a reliable 30A at 240V protection is required.
