Eaton QHCX3080H Miniature Circuit Breaker - 42 kAIC UL Listed
Part Number: QHCX3080H
Quick Summary
The Eaton QHCX3080H miniature circuit breaker is a thermal-magnetic protective device designed for industrial control panels and machine wiring. It delivers reliable overload and short-circuit protection in a compact, three-pole form factor, reducing space while guarding critical networks. Engineers often face nuisance trips or slow response on high-inrush equipment; this unit’s thermal-magnetic trip curve balances sensitivity with selectivity to minimize downtime. The QHCX3080H carries UL Listed and CSA Certified ratings, ensuring compliance across North American installations. With a 3-pole, 240 V design and an 80 A rating, it supports three-phase feeders while maintaining safe, predictable protection. Its cable-in/cable-out termination and modest 2.9 in depth simplify field wiring and panel layout, delivering faster installation and lower total cost of ownership.

FAQs
The QHCX3080H is a three-pole, 240 V circuit breaker designed for three-phase panels. Its cable-in/cable-out termination and compact footprint simplify installation in industrial control enclosures, reducing wiring complexity and panel depth while delivering consistent phase protection and predictable trip behavior.
This device uses a thermal-magnetic trip mechanism with a 42 kAIC interrupt rating and an 80 A current rating, providing fast isolation for short circuits while preventing nuisance trips on normal inrush. The T268 trip curve supports balanced protection across all three poles in line with standard industrial protections.
Yes. The 42 kAIC interrupt rating offers robust fault-current handling suitable for motor loads and equipment with higher inrush. Pairing this with precise thermal-magnetic coordination minimizes nuisance trips while ensuring rapid disconnection during true faults.
The QHCX3080H is UL Listed and CSA Certified, providing recognized safety approvals for North American installations and helping meet regulatory requirements for industrial control panels and wiring.
It features cable-in/cable-out termination for straightforward wiring, a compact footprint (2.9 in deep x 3.4 in wide x 3.5 in high) and a lightweight 1 lb weight, enabling faster mounting, reduced panel depth, and simpler service in OEM equipment and distribution panels.
