FAQs
The QPHW3090H uses a plug-on mounting with fixed terminals for three-pole installation. Align the unit with the bus structure, secure it firmly, and connect conductors to the fixed terminals. Its compact 3.8 in depth and 3.2 in width help maximize panel density while ensuring proper torque and conductor termination per standard practices.
The 22 kAIC interrupt rating indicates the breaker can safely interrupt high fault currents typical of motor starts and short circuits. This reduces the risk of arc flash, protects downstream equipment, and helps maintain uninterrupted production in motors, drives, and conveyors within manufacturing environments.
Yes. The unit is UL Listed and CSA Certified and HACR rated. This combination supports NEC/CEC compliance, enables safer operation in HVAC and general industrial equipment, and simplifies regulatory audits for facilities that require certified protection devices in control panels.
The breaker measures 3.8 in in depth, 4.7 in in height, and 3.2 in in width, weighing 1.2 lb. It features a fixed-terminal design with plug-on mounting, ideal for compact enclosures and retrofit projects where space optimization and secure electrical connections are priorities.
The QPHW3090H reduces downtime through reliable trip protection, minimizes maintenance costs with a durable thermal-magnetic mechanism, and simplifies installation with plug-on mounting. Coupled with a 1-year warranty and readily available spare parts, it supports predictable budgeting and lower total cost of ownership in industrial environments.
