BQ3D050 - 50Amp Circuit Breaker Description
BQ3D050 - 50 Amp Circuit Breaker
If you’re replacing a 50-amp three-pole breaker in a compatible BQ panelboard, the BQ3D050 is built for the job. This bolt-on molded case circuit breaker is rated 50 amps with a 10k A.I.C. at 240VAC, making it suitable for three-phase branch circuits in commercial and light industrial settings. It mounts directly to the bus in approved BQ-style equipment, helping ensure proper contact and a secure fit. With a 40°C rating and HACR certification, it’s commonly used in HVAC and refrigeration applications as well as other motor-driven loads. Like breakers in this class, it’s built to last when installed and maintained correctly.
Designed around the BQ frame type, the BQ3D050 focuses on what matters most in replacement projects: correct amperage, correct interrupting capacity, and the right mounting configuration for existing systems.
