Overview
The Eaton Cutler-Hammer CHT2020 is a Type CHT twin circuit breaker offering a compact, space-efficient solution for residential and light commercial panel expansions. This 20A/20A dual-pole tandem breaker plugs directly into Type CH Eaton loadcenters, maximizing circuit capacity without requiring a subpanel. With thermal-magnetic trip technology and 10 kA interrupting capacity at 240VAC, it delivers reliable protection for general-purpose branch circuits and HVAC/lighting control applications.
