Eaton CHP125 Circuit Breaker - UL 489
Part Number: CHP125
Quick Summary
Eaton CHP125 circuit breaker delivers reliable overcurrent protection for Type CH load centers in commercial and light-industrial panels. Nuisance trips and lengthy replacements slow projects; this plug-in CHP125 simplifies upgrading and commissioning. UL 489 certification, HACR rating, and compatibility with Type CH load centers ensure safe, code-compliant protection across typical distribution panels. With a 25 A rating at 120/240 V and wiring for #14-6 AWG Cu/Al, the CHP125 supports modular, standardized electrical protection that reduces spare parts and stocking complexity. This makes it easier for engineers and procurement teams to specify, source, and install reliable protection quickly, while maintaining performance across evolving industrial control and power distribution schemes.

FAQs
The CHP125 is a plug-in, single-pole breaker rated at 25 A and 120/240 V, designed for Type CH Loadcenters. Installers should ensure proper alignment with CHP main components, verify conductor sizing to #14-6 AWG Cu/Al, and confirm UL 489 listing. Its HACR rating supports HVAC-related loads, while the 10 kAIC interrupt rating provides robust fault protection during panel maintenance and upgrades.
CHP125 provides a 10 kAIC interrupt rating at 120/240 VAC, meaning it can safely interrupt high fault currents typical in distribution systems without losing protective coordination. This rating helps meet NEC requirements for branch-circuit protection, reduces the risk of arcing damage, and supports reliable operation in commercial and light-industrial panels during fault events.
Yes, the CHP125 is HACR rated, which means it is suitable for circuits that supply heating, air conditioning, and refrigeration equipment. This rating simplifies compliance in buildings with HVAC loads, reduces the need for separate cross-listing, and supports safer, code-conforming protection for mechanical spaces and comfort systems.
CHP125 is designed for Type CH Loadcenters and is intended for use as a plug-in replacement within that family. Compatibility with Type CH Loadcenters ensures consistent electrical protection, streamlined stocking of Type CHP components, and quicker retrofits or upgrades in both new installations and service upgrades.
Official Eaton documentation includes the CHP125 specification sheet and the Type CH circuit breaker warranty. Access the CHP125 datasheet for detailed electrical characteristics and installation notes, and review the warranty document for coverage terms and limits. Both resources help validate compliance, support maintenance planning, and justify lifecycle costs in procurement.
