CHB315 - 15Amp Circuit Breaker

CHB315 - 15Amp Circuit Breaker

The Eaton CHB315 is a 15 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 panel setup. Even though it’s a lower amp rating, it still serves an important role in 240V three-pole circuits, where all three conductors need to disconnect together to keep the system operating the way it was originally designed.

In real-world use, this breaker usually shows up in residential and light commercial panels where smaller three-pole loads are part of the system. Most of the time, it’s used for straightforward replacement work—matching what’s already installed so the panel stays consistent and nothing in the layout has to change. Installation is simple in compatible Eaton CH Loadcenters. The plug-in design allows the breaker to seat directly into the panel without modification, which helps keep your replacement work quick and predictable when working inside an existing CH system.

At its core, the CHB315 is a direct replacement breaker for Eaton CH Loadcenters. It’s meant to keep existing systems consistent and operating as originally configured, without changing the panel layout or creating compatibility issues.
