CHH2225 - 225Amp Circuit Breaker

CHH2225 - 225Amp Circuit Breaker

The CHH2225 225 Amp molded case circuit breaker is the kind of part you end up using when you’re working inside an existing CHH-series panel and the job is to replace what’s already there without changing the system around it. In most cases, it’s a straightforward like-for-like swap—same style, same footprint, same electrical ratings—so the panel can stay exactly as it was designed.

This breaker is commonly found in 240VAC feeder and distribution circuits, especially in commercial and industrial electrical rooms where equipment has been in service for years. The two-pole setup is standard for this type of application, since both conductors need to disconnect at the same time when the system sees an overload or fault. It’s a familiar configuration for electricians working in established panels.

The 100kA interrupting rating at 240VAC is there to match higher available fault current conditions found in many of these systems. In practice, it’s not about changing anything—it’s about making sure the replacement breaker lines up with what the system already requires so everything stays within its original design limits. This model also uses a non-interchangeable trip unit, which keeps things simple in the field. There’s no adjusting or swapping components—the protection is set at the factory and stays that way. For maintenance work, that usually means fewer steps and less time spent verifying configurations during replacement.

Most of the time, the CHH2225 gets installed during routine maintenance or repair work.
