MA3225 - 225 Amp Circuit Breaker

MA3225 - 225 Amp Circuit Breaker

The MA3225 is a 225-amp, 3-pole MA thermal-magnetic circuit breaker with an interchangeable trip unit, a 40°C rating, and load-side terminals included. When sourcing a breaker for your existing or legacy electrical equipment, matching the details is what counts. If the amperage, pole count, MA type, trip-unit configuration, terminal arrangement, dimensions, and A.I.C. ratings match the application requirements, the MA3225 can be considered a form, fit, and functional replacement candidate for compatible electrical equipment.

Key Features and Benefits

• 225 Amp Rating: Rated at 225A for applications requiring this specific current rating.
