Eaton CL220CS Circuit Breaker - 10 kAIC UL 489
Part Number: CL220CS
Quick Summary
The Eaton CL220CS circuit breaker delivers reliable thermal-magnetic protection for CH load centers used in commercial and light-industrial panels. When you replace aging gear, exact form factor, rotation, and cross-brand compatibility are critical to avoid panel rework. UL 489 certification and classification as a CH load-center replacement help ensure safe, code-compliant operation. With 20 A at 120/240 V and a two-pole, common-trip configuration, it fits a broad range of circuits. This clamshell-pack solution simplifies stocking and installation, reducing downtime and enabling faster repair cycles. It is a replacement for multiple OEM breakers, including cross-reference to Square D Homeline and GE THQ, saving inventory variety. Designed for CH load centers requiring two 1-inch spaces, it supports straightforward installation with standard grounding and wiring practices.

FAQs
Yes, the CL220CS is designed as a classified replacement for CH Load Centers. It is a two-pole, 20 A device rated at 120/240 V with a common-trip configuration and uses #14-4 AWG Cu/Al conductors. It requires two 1-inch panel spaces. For installation, verify panel compatibility, remove the existing breaker, ensure bus connections are clean, connect conductors to the CL220CS terminals, and secure the unit per enclosure guidelines.
Key specs include 20 A amperage rating, 120/240 V operating voltage, two poles, and a 10 kAIC interrupt rating. It is UL 489 certified and classified for cross-brand replacement with CH load centers. The unit uses #14-4 AWG Cu/Al conductors and is packaged in a clamshell to simplify deployment in field installations.
The CL220CS is best suited for CH load centers in commercial and light-industrial panels, including main distribution and subpanels. Its common-trip, two-pole design supports multi-circuit protection on shared feeders, while the 10 kAIC rating makes it suitable for moderate fault-current environments. Its cross-brand compatibility also supports mixed-brand panel configurations.
The CL220CS carries UL 489 certification, confirming adherence to recognized safety and performance standards for low-voltage circuit breakers. This certification supports compliance in most electrical installations and helps meet code requirements for protective device replacements in CH load centers.
Stocking CL220CS improves ROI by reducing part spares diversity through cross-brand compatibility with several popular breakers, enabling a single part to serve multiple panel brands. The clamshell packaging also simplifies inventory handling, while the common-trip, two-pole design minimizes maintenance checks and improves uptime in daily operation.
