Eaton CHF335SW CH Thermal Magnetic Circuit Breaker - UL 489
Part Number: CHF335SW
Quick Summary
Eaton CHF335SW is a three-pole thermal-magnetic circuit breaker for main and branch protection in CH Loadcenters. Engineers often face compatibility gaps, nuisance trips, and mounting challenges when upgrading panel protection in aging installations. This unit is UL Listed 489, HACR rated, and supports 120/240 V operation, delivering reliable performance under high fault currents. By pairing with Type CHF plug-on breakers and Type CH Loadcenters, it streamlines wiring, reduces installation time, and minimizes panel footprint. Its 10 kAIC interrupt capacity, common-trip design, and switching neutral enhance safety and coordination across all poles, supporting compliance and ongoing maintenance. With a limited lifetime warranty and clearly documented specifications, it offers a compelling value for OEMs, distributors, and maintenance teams.

CHF335SW is a three-pole Type CHF plug-on circuit breaker rated at 35 A for use in CH Loadcenters. Feature → Business Impact → Application: The three-pole design enables coordinated protection across all phases, reducing the risk of interphase faults and improving system reliability in three-phase motors and distribution panels. Application: industrial automation panels and commercial electrical distribution. Plug-on mounting simplifies installation and replacement, accelerating commissioning and minimizing panel downtime; this supports faster line starts and easier field service for maintenance teams. Interrupt rating of 10 kAIC ensures robust fault handling for typical industrial fault currents, while UL 489 listing and HACR rating provide regulatory confidence and safer long-term operation. Feature → Business Impact → Application: Common trip across poles ensures coordinated tripping and reduces the chance of arc flash or asymmetric faults; applicable to Type CH Loadcenters in control rooms and machine rooms. Wire compatibility with #14-6 AWG Cu/Al offers flexible termination options and cost-effective field wiring. Benefit: a compact, reliable protection solution with extended service life and reduced total cost of ownership.
