Eaton Specification Sheet - CHF120CS
Eaton type CH circuit breaker limited warranty June 2024
Thermal magnetic trip mechanism delivers precise protection against both overloads and short circuits, reducing the risk of nuisance tripping and equipment damage. With a 10 kAIC interrupt rating and a single-pole CHF design rated for 120/240 V, it aligns with common panel architectures and supports predictable coordination within Type CH load centers. The mechanism’s fast, predictable response translates into fewer unplanned outages and improved uptime in industrial and commercial buildings. Clamshell pack packaging reduces bulk handling and shipping costs; procurement teams appreciate simplified stocking. This packaging style also supports bulk orders and easier inventory management in warehouses and job sites, enabling faster pull from shelves and reducing breakage risk during transport. Wire-size compatibility ensures straightforward field termination: two #14-10 AWG Cu/Al conductors and one #14-8 AWG conductor accommodate typical feeders and branch circuits. The single-pole 20 A rating covers everyday lighting and general-purpose circuits, while the 3/4-Inch CH footprint fits tight panel spaces. UL Listed and CSA Certified with HACR rating ensures regulatory compliance and safe operation with HVAC equipment; designed for residential, commercial, and light industrial panels. For Type CH Load Centers, CHF120CS offers reliable protection within Eaton’s CH ecosystem, backed by a limited lifetime warranty and streamlined maintenance that support lower total cost of ownership.
