BQ2B100H - 100Amp Circuit Breaker

BQ2B100H - 100Amp Circuit Breaker

The Siemens BQ2B100H is a 100-amp, 2-pole molded case circuit breaker designed for you to use in 120/240V electrical distribution systems. It provides overcurrent protection for your branch and feeder circuits and utilizes a common-trip mechanism that opens both poles when a fault occurs. As part of the Siemens BQH series, this breaker is often specified for applications where a higher interrupting rating is required.

For contractors and maintenance personnel, the BQ2B100H is a familiar option when replacing existing Siemens breakers or completing new installations in compatible equipment. Its combination of a common-trip design, bolt-on mounting, and higher fault-current rating makes it suitable for a wide range of electrical distribution applications.
