BQ2B050H - 50Amp Circuit Breaker

BQ2B050H - 50Amp Circuit Breaker

The Siemens BQ2B050H is a 50 amp, 2-pole circuit breaker designed for you to use in Siemens Type BQH panelboards and electrical distribution equipment. Rated for 120/240 VAC, it uses a common-trip thermal magnetic mechanism that disconnects both poles during overload or short-circuit conditions.

Its 22 kAIC interrupting rating makes it suitable for your systems with higher available fault current than standard 10 kA breakers. The bolt-on configuration mounts directly into compatible Siemens equipment, and load-side lugs are included. A 50 amp, 2-pole breaker is commonly used for HVAC equipment, electric water heaters, pumps, compressors, machinery, and other dedicated 240-volt loads. The BQ2B050H is UL 489 Listed for branch circuit protection and is used in residential, commercial, and industrial electrical systems.
