CHH3225 - 225Amp Circuit Breaker

CHH3225 - 225Amp Circuit Breaker

The CHH3225 is a 225 Amp, 3-pole CHH molded case circuit breaker designed for you to use in commercial and industrial electrical distribution systems where matching the original breaker specifications is important. Rated 100kA at 240VAC, this breaker is commonly found in applications where the existing system was designed around a higher interrupting capacity and requires a replacement that maintains those original ratings.

One of the key reasons electricians and maintenance teams look for the CHH3225 is simple: compatibility. When your breaker in an established system needs to be replaced, matching the amperage, pole configuration, interrupting rating, and frame style helps keep the electrical design unchanged. This breaker provides the form, fit, and functional characteristics expected in installations that require a 225 Amp, 3-pole CHH breaker with a non-interchangeable trip unit.

Its molded case construction is intended for long-term service in properly maintained electrical equipment. You'll commonly find breakers like this protecting feeders, distribution equipment, and other three-phase circuits in commercial buildings and industrial facilities. Rather than changing the panel layout or protection scheme, the CHH3225 allows the existing system to remain configured as originally designed.
