CHB120GF - 20Amp Circuit Breaker

CHB120GF - 20Amp Circuit Breaker

The CHB120GF is a 20 Amp single-pole ground fault breaker used in Eaton CH Loadcenters. It’s mainly used as a replacement breaker in existing CH panel installations where matching the original breaker type and rating is needed.

You’ll typically find this breaker on lighting circuits, receptacles, and other standard 120V branch circuits. It also gets used in setups where ground fault protection is required, including some HID lighting applications noted by the manufacturer. Since it’s a CH plug-in style breaker, it installs directly into compatible loadcenters without any modification.

This breaker includes 5 mA ground fault protection, used where that level of protection is specified. It operates using a thermal magnetic trip, which handles overloads and short circuits during normal circuit use. The CHB120GF is rated for 120/240V systems and has a 10kA interrupting rating. It’s commonly used in residential and light commercial panels built around Eaton CH equipment, especially when replacing existing breakers and keeping everything consistent inside the panel.

In most cases, this breaker is selected simply because it matches what’s already in place, making replacement work straightforward.
