CHB230GF 30Amp Circuit Breaker

CHB230GF 30Amp Circuit Breaker

The Eaton CHB230GF is a 30 Amp, two-pole circuit breaker designed for use in Eaton CH Loadcenters, especially when you need a direct replacement that keeps the original panel layout intact. It’s built for 120/240V circuits where both legs need to disconnect at the same time, and it fits right into existing CH series panels using a plug-in style that makes replacement work pretty straightforward.

In real-world use, this breaker shows up in residential and light commercial systems where ground fault protection is required on a 2-pole circuit. The built-in 5 mA ground fault feature is the main standout here—it adds that extra level of protection for circuits that need it, without changing the way the CH Loadcenter is set up. Installation is simple in most cases. Since it uses the standard Eaton CH plug-in design, it snaps into compatible panels without any modifications. If you’re replacing an existing CH breaker, it’s usually a clean swap that helps keep maintenance work quick and consistent.

Inside, the CHB230GF uses a thermal magnetic trip system, which handles both slow overload conditions and sudden short-circuit events. It’s rated at 10 kAIC interrupt capacity, which lines up with typical fault levels found in standard residential and light commercial CH panel installations.

With support for #8–4 AWG wiring, it’s suited for larger branch circuits where heavier conductors are used.
