FAQs
CHF220CS is designed for Type CH Loadcenters and uses a two-pole configuration suited for 120/240 V circuits. Wire size compatibility includes (2) #14-10 AWG Cu/Al for main conductors and (1) #14-8 AWG for the alternate path in applicable configurations. The device arrives in a clamshell pack for straightforward handling and inventory control, simplifying field installs and replacements.
The 10 kAIC interrupt rating means the CHF220CS can safely interrupt fault currents up to 10,000 amperes, reducing the likelihood of arcing, equipment damage, and downstream failures. This capability improves reliability for feeders and circuits that may experience high transient currents, particularly in commercial or multi-load panel assemblies that share service entrances.
Yes. The CHF220CS is a 20 A two-pole unit rated for 120/240 V, making it well-suited for typical residential branch circuits and light commercial panels. It pairs with Type CH Loadcenters to provide organized, code-compliant protection for essential HVAC, lighting, and outlet circuits while keeping installation straightforward and standardized.
The CHF220CS is HACR Rated and CSA Certified UL Listed, ensuring performance compliance with electrical codes and safety standards. HACR rating indicates suitability for air conditioning and heating loads, which helps prevent nuisance trips. UL listing and CSA certification offer third-party validation, supporting warranty coverage and regulatory acceptance across jurisdictions.
Eaton provides a Limited Lifetime warranty on the CHF series, reflecting confidence in longevity and reliability. Regular inspection during panel maintenance, proper torque on terminations, and using the specified wire sizes help minimize nuisance trips and extend service life. The clamshell packaging also simplifies stocking and rapid replacement, reducing downtime and maintenance costs.
