MPP2125KM - 125 Amp Circuit Breaker

MPP2125KM - 125 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the catalog number is only the starting point. MPP2125KM is identified as a 4-pole, 120/240V Type MPP-MT thermal-magnetic circuit breaker with a 125A, 65K product designation. The technical information also identifies a plug-in connection and a Marine 50C special feature. That combination of specifications makes matching the breaker to the original equipment especially important.
