BQ3D030 - 30Amp Circuit Breaker

BQ3D030 - 30Amp Circuit Breaker

The Challenger BQ3D030 is a 30-amp, 3-pole circuit breaker designed for use in 240VAC electrical systems. It features a bolt-on mounting design and a Type BQ frame, making it a direct replacement for compatible Challenger panel applications. The common-trip mechanism opens all three poles together when a fault is detected, which is important in three-phase systems where all conductors need to disconnect at the same time.

With a 10kA interrupting rating, the BQ3D030 is commonly found protecting HVAC equipment, motor loads, lighting panels, and general power distribution circuits. For facilities that still rely on Challenger equipment, matching the correct breaker helps you maintain the original panel configuration and keeps maintenance work straightforward. This HACR-rated breaker was built for your everyday electrical service and continues to be used in many commercial, industrial, and multi-unit residential installations.
