CHB3080 - 80Amp Circuit Breaker

CHB3080 - 80Amp Circuit Breaker

The Eaton CHB3080 is an 80-amp, three-pole circuit breaker designed for your Eaton CH Loadcenters and is typically used as a direct replacement for an existing three-pole breaker in an installed panel. It’s built for 240V circuits where all three legs need to trip together, and it installs into compatible CH series loadcenters using a plug-in style that keeps the original panel layout intact.

In everyday use, this breaker is found in residential and light commercial systems handling three-pole 240V loads. Most of the time, it’s used in replacement situations where the goal is simple—match what’s already there so the panel keeps working the way it was originally set up.

Installation is straightforward in compatible Eaton CH Loadcenters. The plug-in design allows the breaker to seat directly into the panel without modifications, which helps you keep maintenance work quick and consistent when working inside an existing CH system. Inside, the CHB3080 uses a thermal-magnetic trip mechanism that reacts to both overload conditions and short circuits as they occur. It’s rated at 10 kAIC, which matches typical fault levels found in residential and light commercial CH installations. With support for #4–1/0 AWG wire, it’s suited for heavier three-pole circuits that require larger conductors. The three-pole design ensures all conductors disconnect simultaneously, which is important for balanced 240V applications.

At its core, the CHB3080 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 wiring setup.
