NM632225 - 225Amp Circuit Breaker Description
NM632225 225 Amp 3-Pole Bolt-On Circuit Breaker – 600VAC, 22kAIC
When you're maintaining an existing electrical distribution system, finding the right replacement circuit breaker is about more than matching the amperage. The breaker needs to fit the equipment, connect correctly, and provide the electrical protection specified for the installation. The NM632225 225 Amp 3-Pole Bolt-On Circuit Breaker is a thermal-magnetic molded-case circuit breaker designed for equipment approved for its NM-frame configuration. With a 225-amp current rating, three-pole design, and voltage-specific interrupting capacities, it provides a form-, fit-, and function-replacement option for compatible legacy electrical systems.
The breaker also has a 40°C temperature rating and uses molded-case construction to enclose its switching and protective components. It's built for long service life, though actual service life depends on installation conditions, electrical loading, maintenance, and operation within the specified ratings.
