Eaton Specification Sheet - CL220
The 1-Inch classified CL220 occupies two spaces in CH load centers, delivering a compact solution that simplifies panel layout and reduces mounting complexity. This translates to faster installations, lower labor costs, and improved overall panel organization for electrical contractors working on retrofit projects. The two-pole, common-trip design coordinates protection across paired circuits, reducing the risk of nuisance trips and improving fault isolation in dense residential and light commercial distributions. With a 20 A rating and 120/240 V operation, the CL220 protects standard branch circuits while remaining compatible with typical wiring such as #14-4 AWG Cu/Al, enabling straightforward field terminations and reliable performance. Its 10 kAIC interrupt rating provides robust fault current handling in moderate commercial environments, supporting safer retrofits and compliant panel operation. The CL220 is positioned as a versatile replacement for multiple legacy devices, simplifying stocking and procurement for service teams. Compatibility with Type CH load centers helps ensure quick, vibration-free installations and consistent protection in Eaton’s CL family. Industry professionals value the CL220 for predictable trip characteristics, reduced inventory, and reliable performance in everyday electrical distribution tasks.

FAQs
The CL220 is a 1-inch classified replacement designed for Type CH load centers and CH-based panels. It is listed as a replacement for a range of legacy breakers including Square D Homeline and GE THQ in many retrofit scenarios, and it requires two spaces in the panel. This compatibility simplifies stocking and reduces downtime when upgrading legacy installations.
The CL220 is a 20 A breaker rated for 120/240 V with a 10 kAIC interrupt rating. It is a two-pole, common-trip device of Type CH, suitable for protecting branch circuits in residential and light commercial panelboards. These specs deliver coordinated protection and reliable fault clearing for typical distribution systems.
As a classified 1-inch replacement, the CL220 fits into two panel spaces, simplifying installation in CH load centers and reducing field wiring complexity. Its common-trip, two-pole design speeds wiring and testing, while its compatibility with multiple legacy form factors minimizes the need for additional parts and reduces maintenance time on aging installations.
Yes, the CL220 carries UL 489 certification, ensuring compliance with standard safety requirements for circuit breakers. Its 10 kAIC interrupt rating supports higher fault current environments, and its classification as a CH load center replacement aligns with common U.S. electrical standards for residential and light commercial panels.
Upgrading to the CL220 can reduce downtime and spare part complexity by consolidating stocking into a single replacement pattern for CH load centers. The 20 A, 120/240 V, and 10 kAIC specs deliver reliable protection, while the two-space footprint minimizes panel rework. Over time, reduced service calls and faster installs translate to tangible maintenance cost savings.
