Siemens Q250 Circuit Breaker

Siemens Q250 is a 50-amp, two-pole plug-on circuit breaker designed for 120/240-volt residential service, providing a compact, two‑pole solution for protecting high‑demand 240‑volt loads in Siemens QP/Q-Line panels. This unit clips directly onto compatible bus bars in standard Siemens residential panels, making it a straightforward replacement or addition for 240‑V branch circuits such as electric ranges, central air conditioning, or electric water heaters. The Q250 delivers a 50 A rating at 120/240 V and is specified with a 10,000‑amp interrupting capacity (10 kAIC), offering reliable overcurrent protection under typical household load conditions. As a member of Siemens’ QP family of breakers, it is intended for residential distribution applications where a dedicated 240‑volt circuit protection is required, compatible with panels that accept QP/Q-Line plug‑on breakers.
