CHB330 - 30Amp Circuit Breaker

CHB330 - 30Amp Circuit Breaker

The Eaton CHB330 is a 30 Amp, three-pole circuit breaker designed for Eaton CH Loadcenters, and it’s typically used when you need a direct replacement that matches an existing breaker in the panel.

In most cases, this breaker shows up in residential and light commercial panels handling smaller three-pole 240V circuits. It’s usually used in replacement work—matching what’s already installed so the system keeps running the way it was originally designed, without changes to wiring or layout.

Installation is straightforward in compatible Eaton CH Loadcenters. The plug-in design lets the breaker seat directly into the panel without modification, which helps keep your maintenance work simple when working inside an existing system. Inside, the CHB330 uses a thermal magnetic trip system, which responds to both overload and short-circuit conditions. It’s rated at 10 kAIC, which fits standard fault levels found in typical residential and light commercial CH installations. With support for #14–8 AWG conductors, it’s suited for smaller branch circuits that still require a three-pole configuration.

At its core, the CHB330 is a direct replacement breaker for Eaton CH Loadcenters. It’s meant to keep existing systems consistent and operating as originally designed, without changing the panel layout or creating compatibility issues.
