CHB120 - 20Amp Circuit Breaker

CHB120 - 20Amp Circuit Breaker

The CHB120 is a 20 Amp single-pole breaker used in Eaton CH Loadcenters. It’s most often used as a replacement in existing CH panels where the goal is to match the original breaker type and keep the installation consistent.

In practice, this breaker shows up in standard lighting and receptacle circuits, along with other typical 120V branch circuit applications. Because it’s a CH plug-in style breaker, it fits directly into compatible loadcenters without any adjustments, which makes it a common choice for your maintenance and replacement work.

This model includes 5 mA ground fault protection, used in situations where additional protection is required. Inside, it uses a thermal magnetic trip, which handles both overload and short-circuit conditions in normal day-to-day electrical use.

It’s rated for 120/240V systems with a 10kA interrupting rating, and it’s intended for residential and light commercial panels built around Eaton CH equipment. Most of the time, it’s selected simply because it matches what’s already in place in the panel.
