Eaton CHF225 Thermal Magnetic Circuit Breaker - UL 489

Thermal magnetic trip technology provides fast, predictable protection against overload and short circuit events, reducing nuisance trips and improving reliability. The impact is fewer field adjustments and less downtime for critical circuits, especially in residential and light commercial panels. This makes the CHF225 ideal for Type CH Loadcenters with 120/240 V service, where compact space and dependable protection are essential. Two-pole common-trip design ensures simultaneous disconnection of both conductors, enhancing arc-fault safety and simplifying panel coordination. The business impact is simplified wiring schedules and improved code compliance during installation and maintenance. Use in two-pole configurations in CH Loadcenters to prevent single-pole leakage and ensure protective coordination. Amperage rating of 25 A with a 10 kAIC interrupt rating lets circuits handle typical branch circuits and short-circuit faults with a safe margin. The impact: improved protection for modest-load circuits in residential/commercial spaces, reducing equipment damage costs. Applications: branch circuits in 120/240 V systems, service entrance panels. Wiring compatibility specifies (1) #14-8 AWG and (2) #14-10 AWG Cu/Al, enabling flexible connections without splices. Impact: reduces installation time and inventory requirements. Application: CH Loadcenters and meter mains with limited wiring options. UL 489 listing and HACR rating support regulatory compliance and broader compatibility with HVAC equipment and general loads. Impact: easier procurement across construction projects and maintenance contracts; reduces vendor-specific stocking. Application: residential, light commercial, and HVAC control panels.
