Eaton Specification Sheet - CL150CS
Compact footprint and clamshell packaging reduce on-site handling time. This translates to faster stocking and safer installations in crowded panels, especially during retrofit projects. Use with CH Loadcenters to streamline replacements and minimize cabinet space impact. High amperage rating of 45 A provides targeted protection for branch circuits while enabling normal load operation, reducing nuisance trips and downtime on critical circuits. The 120/240 V voltage rating supports typical residential and light commercial single-phase systems, enabling universal compatibility across common panel configurations. A 10 kAIC interrupt rating delivers robust fault protection for shared neutrals and multi-wire branch circuits, improving overall panel reliability. The CL main circuit breaker and Type CL classification offer predictable interchangeability with other classified products, simplifying procurement and maintenance. This solution is designed to accommodate #14-4 AWG Cu/Al conductors, supporting straightforward wiring during panel upgrades.
