Eaton MDSC08 Three Phase Molded Case Circuit Breaker

The Eaton Magnum MDSC08 is a three-pole molded case circuit breaker (MCCB) with a 600 Amp rating, designed for three-phase electrical protection in distribution circuits. It includes a 5LSIG ground-fault interrupter (GFI) and a Digitrip 520 AK electronic trip unit, providing ground-fault sensing integrated with the breaker's trip function to interrupt current when faults are detected. The MDSC08 designation identifies the 3-pole, 600 A configuration within Eaton’s Magnum line, a molded-case device intended for use in industrial electrical installations where reliable overcurrent and ground-fault protection are required. This combination of GFI capability and Digitrip trip technology supports safer operation in three-phase systems and helps ensure timely interruption of fault currents in compatible Eaton Magnum assemblies.
