BQ3D070 - 70Amp Circuit Breaker

BQ3D070 - 70Amp Circuit Breaker

The BQ3D070 is a 70-amp, 3-pole circuit breaker designed for you to use in compatible BQ electrical panels and distribution equipment. Rated for 240VAC, it provides overcurrent protection for three-phase circuits and uses a common-trip design that opens all three poles at the same time if a fault occurs. The bolt-on mounting style helps ensure a secure connection within the panel and makes it suitable for installations where a BQ-frame breaker is specified.

You'll often find breakers like the BQ3D070 in commercial buildings, warehouses, schools, apartment complexes, and light industrial facilities. It is commonly used on feeder circuits, HVAC equipment, motor loads, and other power distribution applications that require a 70-amp, 3-pole breaker. With a 10kA interrupting rating and HACR certification, it is designed for the applications and ratings originally intended for this style of breaker. When maintaining an existing electrical system, matching the correct frame type, amperage, and mounting configuration is important, and the BQ3D070 is built for those compatible installations. Like many BQ breakers still in service today, it was built to last and continues to be used in a wide range of electrical systems.
