Eaton Specification Sheet - CHF235ST
Eaton type CH circuit breaker limited warranty June 2024
Plug-on mounting enables rapid, secure installation on CH load centers, minimizing field wiring and mis-termination risk. This translates to faster commissioning, lower labor costs, and fewer on-site errors during panel upgrades. Ideal for commercial and light-industrial distributions where downtime matters. The CHF235ST delivers a 10 kAIC interrupt rating with HACR compatibility, ensuring robust protection for motor-start and lighting circuits and helping meet NEC and local code requirements. Pairing 35 A with 120/240 V supports common branch-circuit configurations while maintaining safe conductor sizing for #14-2 AWG Cu/Al wiring, streamlining installation in standard electrical environments. Shunt trip included enhances control integration for remote shutdown and access-control schemes, reducing manual intervention and improving safety in critical processes. UL Listed 489 certification and Type CHF designation reinforce compliance across installed base and upgrade projects, while the compact form factor supports Type CH Loadcenters with minimal panel footprint impact. A limited lifetime warranty adds long-term protection for maintenance budgets and ROI.
