Siemens Q250N Circuit Breaker

Siemens Q250N is a 2‑pole, 50 A, 120/240 V AC molded‑case circuit breaker designed for residential distribution panels and other Siemens QP/MP frame installations. It uses a thermal‑magnetic trip for overcurrent protection and is rated for a 10,000 AIC interrupting capacity, making it suitable for common branch circuits in homes and light commercial setups. This plug‑in (QP frame) breaker fits Siemens QP/Molded Case panels and provides common‑trip operation for two poles, enabling simultaneous disconnection of both live conductors. The Q250N is intended for 120/240 V, 50/60 Hz service and is HACR rated for use with heating, air‑conditioning, and refrigeration equipment where applicable.
