Eaton QHCX3100H Miniature Thermal-Magnetic Circuit Breaker - UL Listed
Part Number: QHCX3100H
Quick Summary
Eaton QHCX3100H is a miniature thermal-magnetic circuit breaker that protects industrial control panels from overloads and short circuits. Engineers often struggle with nuisance trips and complex wiring in dense control panels. UL Listed and CSA Certified devices with a 42 kAIC interrupt rating at 240 V provide proven safety and reliability for critical equipment. With a 100 A rating and three poles, it is well suited for medium-load motor circuits in manufacturing lines. Cable-in/cable-out termination simplifies field wiring, reducing assembly errors and installation time for panel builders. For procurement teams, this translates to predictable performance, easier maintenance, and lower total cost of ownership.

Thermal-magnetic trip technology delivers fast response to overloads and short circuits, reducing the risk of equipment damage. In a three-pole 240 V system, this means selective tripping across phases and less downtime. The 42 kAIC interrupt rating provides higher fault current tolerance, enhancing safety and protecting downstream devices in industrial environments. A 100 A rating with three poles supports medium-load motor circuits, enabling reliable protection in modular control panels while minimizing wiring complexity. Cable-in/cable-out connections simplify field wiring, accelerating panel builds and reducing field errors during installation. Certifications UL Listed and CSA Certified ensure compliance with important safety standards, helping you meet regulatory requirements with confidence. The compact footprint (3.3 in W × 3.8 in D × 4.9 in H), 1.25 lb weight, and a 1-year warranty support easy retrofits, spare parts availability, and ongoing service for Eaton’s Quicklag QHCX family. Compatibility with standard bus and terminal layouts reduces replacement downtime and supports scalable panel design.

FAQs
When installing the QHCX3100H, use the cable-in/cable-out termination for streamlined wiring in three-pole, 240 V panels. Ensure secure terminations, adequate clearance for heat dissipation, and proper alignment with existing bus bars. The unit’s 3.3 in width and 4.9 in height fit standard enclosures, while maintaining accessibility for maintenance and testing. This minimizes downtime and simplifies future upgrades.
Yes. The QHCX3100H is designed for 240 V three-phase circuits with a 100 A rating and 42 kAIC interrupt capability, making it suitable for motor control and process panels. Its three-pole design provides coordinated protection across phases, reducing the risk of unbalanced faults and improving overall system reliability in industrial environments.
The QHCX3100H is UL Listed and CSA Certified, signaling compliance with key safety and performance standards recognized in North America. These certifications help accelerate regulatory approvals, support supplier qualification processes, and reduce risk during audits. They also reassure maintenance teams and procurement that the device meets established reliability and safety criteria for industrial electrical installations.
A 42 kAIC interrupt rating means the breaker can safely interrupt high fault currents without deforming or failing, protecting upstream equipment and cabling. In densely wired panels, this reduces the likelihood of cascading faults, minimizes arc-flash exposure risk, and supports longer equipment life by containing fault energy within the breaker. This is critical for high-energy industrial environments.
The QHCX3100H carries a 1-year warranty, reflecting Eaton’s confidence in long-term performance for standard industrial duty. Its compact footprint and reliable thermal-magnetic trip reduce maintenance frequency and spare parts needs in busy facilities. Over the life of a panel, this translates to lower total cost of ownership through fewer false trips, simpler parts management, and straightforward field servicing.
