Siemens Q2125 is a two-pole, 125-amp Type QP circuit breaker designed for 120/240 VAC residential and light‑commercial service, using a plug‑in (snap‑in) style compatible with Siemens QP/MP panels. It provides a 10,000‑amp interrupt rating (IR) and relies on thermal‑magnetic trip for standard‑trip protection. Available as Q2125 or Q2125P, this 2‑pole, 125 A breaker is a common replacement in Siemens load centers.
