BQ3B100 - 100Amp Circuit Breaker Description
BQ3B100 - 100Amp Circuit Breaker
The Siemens BQ3B100 is a 100-amp, 3-pole circuit breaker designed for use in 240-volt electrical distribution systems. It provides overcurrent and short-circuit protection for three-phase circuits and uses a common-trip design that opens all three poles at the same time when a fault occurs. This helps protect your wiring, equipment, and connected loads throughout the system.
Part of the Siemens Type BQ breaker family, the BQ3B100 is commonly installed in commercial buildings, warehouses, schools, manufacturing facilities, and other locations that rely on three-phase power. The bolt-on mounting design provides a secure connection in compatible panelboards, and load-side lugs are included to help simplify installation. With a 10kA interrupting rating, this breaker is suitable for a variety of branch circuit and feeder applications where a 100-amp, 3-pole breaker is specified.
Whether you're replacing an existing breaker or working on a new installation, the BQ3B100 offers the ratings and configuration needed for many everyday power distribution applications. Like other Siemens molded case breakers, it is built for long-term service and designed to meet the demands of regular operation.
