BQ2B090H - 90Amp Circuit Breaker

BQ2B090H - 90Amp Circuit Breaker

The Siemens BQ2B090H is a 90-amp, 2-pole molded case circuit breaker designed for your 120/240V electrical distribution systems. It provides you with overcurrent protection for branch and feeder circuits and features a common-trip mechanism that opens both poles during a fault condition. The breaker is part of Siemens' BQH series and is rated for applications where a higher interrupting capacity is required.

This breaker includes load-side lugs and utilizes a bolt-on connection for installation in compatible panelboards and distribution equipment. With a 22 kA interrupting rating, the BQ2B090H is often specified for commercial facilities, multifamily properties, schools, office buildings, retail spaces, and light industrial environments. It is also used in HVAC equipment, feeder circuits, and other electrical distribution applications that require a 90-amp, 2-pole circuit breaker.
