CHB2100 - 100Amp Circuit Breaker

CHB2100 - 100Amp Circuit Breaker

The CHB2100 is a 100 Amp two-pole breaker used in Eaton CH Loadcenters. It’s most often used when replacing an existing CH breaker in a panel where you need the same style, rating, and physical fit to keep everything consistent.

In real-world use, this breaker shows up on larger residential and light commercial circuits—things like subpanels, feeder circuits, or heavier 120/240V loads. Since it’s part of the CH plug-in series, it installs directly into compatible loadcenters without any modification, which keeps replacement work simple in panels that are already in place. Inside, it uses a thermal magnetic trip, which responds to both overloads and short circuits during normal operation. It’s the same basic protection approach used throughout CH Loadcenter systems, designed to work with equipment already built around this platform.

The CHB2100 is rated for 120/240V systems with a 10kA interrupting rating. It’s commonly used in residential and light commercial installations where Eaton CH panels are already installed and the goal is to replace like-for-like without changing the setup.

Most of the time, it’s chosen simply because it matches what’s already in the panel, keeping the system consistent and getting equipment back in service without adjustments.
