997227 - 225 Amp Circuit Breaker

997227 - 225 Amp Circuit Breaker

When you're working with existing electrical gear, the last thing you want is a mismatch. The 997227 molded case circuit breaker is built to line up with the systems that already rely on an ML-3 (J-Frame) configuration, giving you a straightforward replacement option without the guesswork. Rated at 225 amps and designed for 600VAC applications, this 2-pole breaker handles substantial electrical loads while protecting your equipment from overloads and short circuits. This is a thermal-magnetic breaker, meaning it reacts differently depending on the situation—slower response for sustained overloads and immediate action when there’s a short circuit. That balance is exactly what many established systems were designed around. If you're maintaining or restoring an installation, this breaker keeps things consistent with how the system was originally built. And like many breakers of this class, it’s made with durability in mind, ready to stay in service over the long haul.
