The thermal-magnetic trip mechanism provides coordinated protection for both overloads and short circuits, reducing nuisance trips while ensuring rapid fault clearing. Business impact: improved equipment uptime and more predictable panel operation in variable load conditions, which translates to fewer production interruptions and lower service costs. Application: motor control centers, feeders, and power distribution in manufacturing lines benefit from reliable, industry-standard protection. The 80 A rating paired with a 42 kAIC interrupt capacity enables safe interruption of high-energy faults at 120/240 V, supporting robust protection for medium-size circuits in industrial plants. Cable-in/cable-out termination simplifies wiring, enabling faster panel builds and easier field maintenance with fewer loose connections. Certifications from UL Listed and CSA Certified support regulatory compliance and project approvals. The compact footprint (3.8 in L x 4.8 in H x 2.3 in W) and light 0.85 lb weight improve install flexibility in crowded panels. This device aligns with Eaton Quicklag families for consistent protection across assemblies while offering a straightforward replacement path when service is required.

FAQs
When installing the QHCX2080, plan for a two-pole, 120/240 V configuration with cable-in/cable-out termination to simplify wiring. Its compact dimensions (3.8 in L, 4.8 in H, 2.3 in W) fit dense panel spaces, and a weight of about 0.85 lb makes field handling easier. Ensure panel slots and conductor sizing comply with local codes and UL CSA requirements.
The device combines an 80 A continuous current rating with a 42 kAIC interrupt capacity, enabling safe interruption of high-energy faults at 120/240 V. This reduces the risk of cascading faults in feeders and branch circuits while maintaining reliable protection during overloads. The thermal-magnetic trip mechanism provides balanced protection against both sustained overloads and short circuits.
QHCX2080 is part of Eaton’s QHCX family with a non-interchangeable option configuration, ensuring consistent protection characteristics across assemblies. This simplifies device selection for panel builders, reduces the risk of incorrect substitutions, and supports predictable maintenance and spare part inventories in automated facilities.
The QHCX2080 is UL Listed and CSA Certified, indicating conformity with key safety and performance standards required in North America. These certifications streamline code compliance, support approval in panel builds and machine installations, and help minimize project risk when deploying in regulated industrial environments.
Adopting the QHCX2080 can reduce downtime due to nuisance trips and provide consistent protection, lowering maintenance interventions. The 1-year warranty adds supplier confidence, while reliable interruption performance at 42 kAIC enhances system reliability. Over time, this translates to lower spare-part needs, fewer unscheduled outages, and faster commissioning for panel builders and integrators.
