QBHW3080HS - 80 Amp Circuit Breaker

QBHW3080HS - 80 Amp Circuit Breaker

The QBHW3080HS is a 3-pole, 80-amp bolt-on thermal magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection for your commercial and industrial electrical distribution systems. Built as part of the QBHW series, this breaker features a 120V AC shunt-trip device, allowing it to be remotely tripped when connected to an external control circuit. This added functionality makes it an excellent choice for applications that require emergency shutdown capabilities, safety interlocks, or automated power control. Rated for 22kA interrupting capacity at 240VAC, the QBHW3080HS is engineered to interrupt high fault currents while helping you protect connected equipment from electrical damage. Its Quicklag design, HACR rating, 40°C calibration, and bolt-on mounting provide secure installation and dependable operation in demanding environments where consistent performance is essential.
