997327 - 225 Amp Circuit Breaker

997327 - 225 Amp Circuit Breaker

When you're working with an existing electrical system, the last thing you want is guesswork. The 997327 molded case circuit breaker is built to match the specifications your setup already calls for—no modifications, no surprises. With a 225 amp rating, 3-pole design, and support for 600VAC systems, this breaker is commonly used in commercial and industrial panels where dependable circuit protection matters. This unit uses a thermal-magnetic trip mechanism, which means it reacts differently depending on the problem—handling steady overloads one way and sudden faults another. That balance helps keep your equipment protected without unnecessary interruptions. The ML-3 (J-Frame) sizing also makes it a straightforward fit for panels designed around this format, which is often the deciding factor when maintaining older or existing installations. It’s a practical, no-nonsense solution—built the way these breakers have been for years, with durability in mind and a focus on doing the job it’s meant to do.
