The Siemens Q230 Double‑Pole Circuit Breaker is a dependable 2‑pole (2P) breaker engineered to provide reliable overcurrent protection for residential and light commercial electrical systems. Manufactured by Siemens Energy, this breaker is part of the trusted Siemens Q‑Series, known for consistent performance, durability, and compatibility with Siemens load centers.

Rated at 30 amps and approved for 120/240‑volt applications, the Q230 is well suited for protecting moderate‑load 240‑volt branch circuits. As a double‑pole breaker, it connects to both hot bus bars in the panel and ensures simultaneous tripping of both poles, providing proper protection for 240‑volt circuits while supporting safe and code‑compliant electrical installations.

The breaker uses Siemens’ proven thermal‑magnetic trip mechanism, offering dependable protection against both sustained overloads and instantaneous short circuits. Designed with a plug‑on mounting system, the Q230 installs quickly and securely in Siemens load centers approved for Q‑Series breakers, delivering long‑term reliability and consistent electrical performance.
