CHB230 - 30Amp Circuit Breaker

CHB230 - 30Amp Circuit Breaker

The Eaton CHB230 is a 30 Amp, two-pole breaker made for Eaton CH Loadcenters, and it’s typically used when you need a direct replacement that matches the original setup inside an existing panel. It’s built for 120/240V circuits where both legs need to trip together, and it drops right into compatible CH panels without any modification.

In most real installations, this breaker shows up in residential or light commercial panels handling dedicated 240V circuits, especially where ground fault protection is required. The built-in 5 mA ground fault feature is the key detail here—it adds that extra level of protection for circuits that need it, without changing the overall CH panel design.

Installation is pretty straightforward. Since it uses the plug-in CH style, you’re not dealing with rewiring or adjustments. If you’re replacing an existing CH breaker, it’s usually a simple remove-and-replace job as long as the panel is already set up for it. Inside, it uses a thermal magnetic trip system, so it reacts to both slow overload conditions and sudden short circuits. It’s rated at 10 kAIC, which covers typical fault levels you’d expect in standard residential and light commercial environments.

The #14–8 AWG wire range lines up with common branch circuit wiring, and the two-pole design ensures both conductors disconnect at the same time, which is what you want for 240V loads or shared circuit protection.

At the end of the day, the CHB230 is really about keeping existing Eaton CH systems working the way they were designed.
