Overview
The Westinghouse BQC230-240 is a 4-pole (quad) molded case circuit breaker in the BQ series, engineered for 240V AC electrical systems. This Type BRD HACR-rated breaker provides dual 30A and dual 40A poles, making it ideal for multi-circuit branch protection in commercial and industrial applications where space and cost efficiency are critical. The breaker offers thermal-magnetic trip protection with feed-thru connections for straightforward panel integration.
