Description
Built for demanding commercial environments, the Eaton QPHW3080H provides reliable thermal-magnetic protection. This three-pole, 80A miniature circuit breaker is a key component of the Quicklag series, offering fast response times to electrical faults. This unit installs into Eaton Pow-R-Line 1 panelboards and legacy Westinghouse load centers. For panels requiring a bolted connection, the QBHW3080H serves as the equivalent substitute. It features a 22kAIC rating at 240VAC and is HACR rated.Specifications

Product FAQs
5 answersWhich panelboards accept the QPHW3080H circuit breaker?
This Quicklag plug-on breaker is compatible with Eaton Pow-R-Line 1 panelboards and legacy Westinghouse panelboards designed for QPHW series breakers.
What is the bolt-on alternative to the QPHW3080H?
If your panelboard requires a bolted connection rather than a plug-on mount, the QBHW3080H is the direct bolt-on equivalent for this 80A, 3-pole breaker.
Is the QPHW3080H suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment motor loads.
How does the QPHW3080H connect to the panelboard bus?
This breaker features a plug-on mounting design, allowing it to snap directly onto the busbar of compatible Eaton and Westinghouse panelboards without requiring mounting screws or bolted connections.
How does the thermal-magnetic trip unit function on this breaker?
The fixed thermal-magnetic mechanism provides dual protection. The thermal component responds to prolonged overloads with a long-time delay, while the magnetic component provides instantaneous tripping during severe short circuits.
