QBHW3100HS - 100 Amp Circuit Breaker

QBHW3100HS - 100 Amp Circuit Breaker

The QBHW3100HS is a 3-pole, 100-amp bolt-on thermal magnetic circuit breaker engineered to provide dependable overcurrent and short-circuit protection for your commercial and industrial electrical distribution systems. Designed as a QBHW Series breaker, this unit features a 120V AC shunt trip device, allowing the breaker to be remotely tripped when connected to an external control circuit—an important feature for emergency shutdown systems, fire safety applications, and other installations requiring remote disconnect capabilities. With a 22kA interrupting rating at 240VAC, the QBHW3100HS is built to help you protect electrical equipment from damaging fault currents while maintaining reliable performance in demanding environments. Its bolt-on mounting design provides a secure installation, while the thermal magnetic trip mechanism delivers responsive protection against both prolonged overloads and instantaneous short circuits. Rated for operation in 40°C ambient environments and carrying an HACR rating, this breaker is well suited for a variety of HVAC, commercial, and industrial power distribution applications where dependable circuit protection is essential.
