BQ3D090 - 90Amp Circuit Breaker

BQ3D090 - 90Amp Circuit Breaker

The BQ3D090 is a 90-amp, 3-pole bolt-on circuit breaker designed for use in compatible BQ electrical panels and distribution equipment. Rated for 240VAC, it provides overcurrent protection for three-phase circuits and features a common-trip design that opens all three poles at the same time when an overload or short circuit occurs. The bolt-on mounting style helps you ensure a secure fit in equipment designed for BQ-frame breakers.

You'll often find the BQ3D090 in commercial buildings, schools, warehouses, apartment complexes, and light industrial facilities. With a 10kA interrupting rating and HACR certification, it is commonly used on HVAC systems, feeder circuits, motor loads, and general power distribution equipment.
