MD-3000 (End-of-Life)

The MD-3000 protective relay provides differential current protection for motors and generators. It is most commonly used as motor differential protection relay. The MD-3000 is a panel-mounted microprocessor-based self-balancing differential current relay, designed for both ANSI and IEC applications. This self-contained device operates from either AC or DC control power and provides true RMS (root-means-square) sensing of each phase differential current.
