GE M60 | Motor Protection System

Comprehensive protection for medium and large motors. The M60, a member of the UR Family, is a full featured relay designed for the protection and management of medium and large horsepower motors. The M60 incorporates advanced features such as an enhanced thermal model, standard and custom thermal limit curves, current unbalance biasing, running and stopped exponential cooling curves, optional RTD modules, and hot/cold motor compensation. Use the M60 in protection applications requiring complex I/O configurations and high-speed communications.


  • Protection and control of most popular construction type medium to large thee-phase induction motors
  • Automation or process control functionality
  • Protection of medium to large synchronous motors when paired with the SPM Synchronous Motor Protection System
  • Stand-alone protection or component in automated substation control system

Key Benefits
