CHB2100H4 - 100Amp Circuit Breaker

CHB2100H4 - 100Amp Circuit Breaker

The CHB2100H4 is a 100 Amp two-pole circuit breaker used in Eaton CH Loadcenters. It’s commonly used in replacement situations where an existing CH breaker needs to be matched for the same fit, rating, and panel compatibility.

This breaker is typically found in residential and light commercial systems on 120/240V circuits such as subpanels, feeder runs, and larger branch circuits. Since it’s part of the CH plug-in family, it installs directly into compatible CH loadcenters without any modification, which helps keep your replacement work straightforward in panels that are already in service. Inside, it uses a thermal magnetic trip mechanism, which responds to overloads and short-circuit conditions during normal circuit operation.

The CHB2100H4 is rated for 120/240V systems and carries a 42kA interrupting rating, making it suitable for your CH installations that require higher interrupt capacity within the same breaker family. In most cases, it’s selected simply to replace an existing unit and keep the panel consistent without changing the layout or design.

These breakers are commonly used in maintenance and repair work where the goal is to replace like-for-like components so the system can continue operating as originally designed.
