BQ2B100 - 100Amp Circuit Breaker

BQ2B100 - 100Amp Circuit Breaker

The Siemens BQ2B100 is a 100-amp, 2-pole molded case circuit breaker designed for use in 120/240V electrical distribution systems. It provides overcurrent protection for your branch and feeder circuits and features a common-trip mechanism that opens both poles during an overload or short-circuit condition. The breaker is part of Siemens' Type BQ product line and is commonly installed in panelboards, load centers, and distribution equipment requiring a 100-amp two-pole breaker.

This breaker utilizes a bolt-on connection and includes load-side lugs. With a 10 kA interrupting rating, the BQ2B100 is suitable for a wide range of electrical distribution applications found in commercial buildings, multifamily properties, schools, office facilities, retail spaces, and light industrial environments.
