BQ3D080 - 80Amp Circuit Breaker

BQ3D080 - 80 Amp Circuit Breaker

The BQ3D080 is a 3-pole, 80-amp bolt-on molded case circuit breaker designed for use in panelboards that require a BQ frame breaker. Rated at 10kA interrupting capacity at 240VAC, it provides essential overcurrent and short-circuit protection for three-phase electrical systems. This unit is HACR rated and calibrated for 40°C operation, making it suitable for HVAC-related circuits and other common commercial applications. The bolt-on design creates a secure mechanical and electrical connection to the panel bus, helping maintain consistent performance over time. Built to last, the BQ3D080 is intended for proper fit and functional replacement in compatible BQ panelboards where matching amperage, voltage, and interrupting capacity is critical.
