QBHW3080H - 80 Amp Circuit Breaker

QBHW3080H - 80 Amp Circuit Breaker

The QBHW3080H is a 3-pole, 80-amp thermal magnetic bolt-on circuit breaker designed to provide dependable overcurrent and short-circuit protection for commercial, industrial, and institutional electrical distribution systems. Built as part of the QBHW series, this breaker features a 22kA interrupting rating at 240VAC, making it well-suited for applications where higher fault current protection is required. Its bolt-on mounting design helps create a secure electrical connection, while the thermal magnetic trip mechanism responds to both prolonged overloads and instantaneous short circuits to help protect equipment and electrical infrastructure. Rated for 40°C operation and HACR applications, the QBHW3080H is an excellent choice for panelboards and distribution equipment serving HVAC systems, motors, lighting, and other demanding branch circuits where consistent performance and reliable protection are essential.
