QBHW3090H - 90 Amp Circuit Breaker Description
QBHW3090H - 90 Amp Circuit Breaker
The QBHW3090H is a 90-Amp, 3-pole thermal-magnetic circuit breaker with a bolt-on Quicklag mounting design. It is rated to interrupt 22 kA at 240 VAC and is intended for use in compatible electrical distribution equipment that requires this level of fault protection.
Thermal magnetic breakers use two methods of protection. The thermal element reacts to overloads that develop over time, while the magnetic element trips almost instantly during a short circuit. This combination helps protect wiring and connected equipment from damage caused by excessive current.
The QBHW3090H carries a 40°C ambient rating and is HACR rated, making it suitable for many heating, ventilation, air conditioning, and refrigeration applications. Its bolt-on construction creates a secure connection inside compatible panelboards, which is often preferred in commercial and industrial installations where equipment is subject to vibration or frequent operation.
When you're replacing an existing breaker, always verify that the part number, electrical ratings, and panel compatibility match the original equipment requirements.
