Eaton CHF240SW Circuit Breaker - UL Listed 489
Part Number: CHF240SW
Quick Summary
The Eaton CHF240SW Circuit Breaker protects electrical circuits in CH load centers, delivering reliable protection in panels. Mismatched breakers and confusing wiring specs routinely slow projects and risk downtime. UL Listed to UL 489 and HACR-rated, this CHF device is designed for Type CH Loadcenters. It features a 40 A ampacity, a 10 kAIC interrupt rating, and plug-on mounting for fast field installation. By aligning with Eaton Type CH Loadcenters and using the same thermal-magnetic protection, you gain predictable maintenance, improved panel reliability, and reduced total installed cost. This is ideal for critical power distribution where downtime is costly and compliance matters. Its compact 1.5 in depth and 5 in width help maximize panel density and simplify retrofits.

The CHF240SW employs a thermal-magnetic trip mechanism with a 40 A rating, 120 V operation, and a 10 kAIC interrupt rating. This precise overcurrent protection reduces fault energy in branch circuits and helps protect downstream equipment in commercial and light industrial panels. Two-pole, plug-on mounting and common-trip construction simplify installation and enhance panel reliability. Field teams benefit from faster retrofits and fewer wiring errors when upgrading Type CH Loadcenters to a compatible CHF device. Wire sizing supports #14-2 AWG Cu/Al conductors, minimizing conductor hassles and enabling clean terminations. The compact footprint aids dense panel layouts, while the trip flag and neutral switching features support safer, more efficient maintenance. UL Listed to UL 489 and HACR rated, CHF240SW meets essential safety standards for commercial installations, reducing project risk and ensuring code compliance. A limited lifetime warranty adds long-term value, while the plug-on design minimizes site labor and inventory complexity for procurement teams.

FAQs
CHF240SW is a two-pole, plug-on device designed for Type CH Loadcenters. It accepts #14-2 AWG Cu/Al conductors, installs quickly with a plug-on method, and uses a common-trip mechanism to ensure both poles trip together. This reduces wiring errors and speeds up retrofits. Ensure panel bus width and mounting fitment align with Eaton CH Loadcenter specifications and follow local electrical codes during installation.
A 10 kAIC interrupt rating indicates the maximum fault current the CHF240SW can safely interrupt without damage. For designers, this provides a clear boundary for fault-current calculations in commercial and light industrial panels. In practice, this rating helps protect downstream equipment and wiring from high-energy faults, contributing to safer, more reliable electrical distribution.
Yes. The CHF240SW is rated 40 A at 120 V and HACR-rated, making it suitable for HVAC and lighting applications within Type CH Loadcenters. Its thermal-magnetic trip reduces nuisance trips from transients, while the 10 kAIC interrupt rating supports typical building fault currents. Always verify circuit load calculations and panel compatibility before deployment.
CHF240SW is UL Listed under UL 489 and HACR rated, ensuring compliance with standard safety and performance requirements for circuit breakers in commercial and industrial panels. These certifications support code conformance, reliable operation in HVAC and general electrical loads, and easier approval during inspections.
The CHF240SW carries a limited lifetime warranty, offering long-term protection for installations in CH Loadcenters. Its plug-on design minimizes field wiring and mis-termination risk, reducing maintenance time. Routine checks should include confirming the trip flag status and inspecting connections for tightness to sustain reliable performance over the panel’s life cycle.
