BQ2B05000S01 - 50Amp Circuit Breaker

BQ2B05000S01 - 50Amp Circuit Breaker

The Siemens BQ2B05000S01 is a 50 amp, 2-pole circuit breaker designed for you to use in Siemens Type BQ panelboards and electrical distribution equipment. Rated for 120/240 VAC, it provides branch circuit protection against overloads and short circuits and uses a common-trip mechanism that opens both poles when a fault occurs.

This model includes a factory-installed 120VAC shunt trip, allowing the breaker to be opened remotely from an external control circuit. That feature is often used in emergency shutdown systems, fire alarm interfaces, safety interlocks, access control systems, and other applications where power must be disconnected from a remote location. The bolt-on design mounts directly into compatible Siemens equipment, and load-side lugs are included. With a 10 kAIC interrupting rating and UL 489 listing, the BQ2B05000S01 is commonly used in commercial, institutional, and industrial electrical systems where both circuit protection and remote tripping capability are required.
