BQ2B100L - 100Amp Circuit Breaker

BQ2B100L - 100Amp Circuit Breaker

The Siemens BQ2B100L is a 100-amp, 2-pole molded case circuit breaker designed for 120/240V electrical distribution systems. It provides overcurrent protection for your branch circuits and feeder circuits and utilizes a common-trip mechanism that opens both poles during an overload or short-circuit condition. This breaker is part of Siemens' Type BQ product family and includes factory-installed line-side and load-side lugs.

The BQ2B100L features a bolt-on connection for installation in compatible Siemens panelboards and distribution equipment. Typical installations include HVAC equipment, distribution panels, feeder circuits, load centers, and other electrical systems requiring a 100-amp, 2-pole circuit breaker.

Line-side and load-side lugs are included as standard equipment, making this model suitable for applications where conductor terminations are required on both sides of the breaker.
