Where It Works Best
The MA3150 150A 3-pole circuit breaker is a practical replacement candidate for compatible existing and legacy electrical equipment that calls for an MA-type, 40°C-rated thermal magnetic breaker with an interchangeable trip unit. This is especially useful when the objective is to maintain the required breaker type, electrical ratings, physical fit, and terminal configuration without changing the original system requirements.
