CHB350 - 50Amp Circuit Breaker

CHB350 - 50Amp Circuit Breaker

The Eaton CHB350 is a 50 Amp, three-pole circuit breaker designed for Eaton CH Loadcenters, and it’s typically used when you need a direct replacement that matches what’s already installed in the panel. It’s built for 240V three-pole circuits where all three conductors need to trip at the same time, and it installs using a plug-in design that keeps the original panel layout unchanged.

In real use, this breaker is usually found in residential and light commercial panels handling mid-range 240V three-pole loads. It’s most often used for replacement work—matching the existing breaker so the system keeps running the way it was originally set up, without changes to wiring or configuration.

Installation is straightforward in compatible Eaton CH Loadcenters. The plug-in style lets the breaker seat directly into the panel without modification, which keeps replacement work simple when working inside an existing system. Inside, the CHB350 uses a thermal magnetic trip system, which responds to both overloads and short circuits. It’s rated at 10 kAIC, which lines up with typical fault levels found in standard residential and light commercial CH installations.

With support for #8–4 AWG wire, it works well for three-pole circuits that need all legs to stay in sync. That shared trip action is important for keeping 240V systems balanced and operating correctly.
