CHH3100 - 100Amp Circuit Breaker

CHH3100 - 100Amp Circuit Breaker

The CHH3100 100 Amp molded case circuit breaker is the kind of part you typically reach for when working inside an existing CHH-series system that already has a defined layout. In most cases, it’s used for replacement or maintenance work where the goal is to keep everything consistent—same footprint, same ratings, same overall setup—so the electrical system continues operating the way it was originally designed.

The 100kA interrupting rating at 240VAC is there to match systems where fault current levels are already known and accounted for. In practice, it’s not about changing the design—it’s about replacing the breaker with one that lines up with the existing electrical requirements so everything stays within spec.

This model uses a non-interchangeable trip unit, meaning the protection settings are fixed from the factory. There’s nothing to swap or adjust in the field, which keeps your installation straightforward and helps reduce variation when doing like-for-like replacements.
