Motor relays

Eaton’s Motor Relays (EMR) provide unparalleled motor protection. These relays are most commonly applied to medium voltage or larger motors. Users appreciate the multiple protection functions, which include zone-selective interlocking and programmable logic control. EMR’s integral test function reduces maintenance time and expense, while the self-diagnostics and reporting increase uptime and simplifies troubleshooting.

Eaton's E-Series Relays

    Core features

    • Integral test function reduces maintenance time and expense. 
    • Zone selective interlocking improves coordination and tripping time, and saves money compared to a traditional bus differential scheme. 
    • Programmable logic control functions to accommodate different control schemes, simplify the wiring of the starter. 
    • Automatically detects direction of the motor and eliminates the need of switching current inputs into the relay. 
    • Reduce trouble shooting time and maintenance costs- Trip and event recording in non-volatile memory provides detailed information for analysis and system restoration. 6000 cycles of waveform capture aids in post fault analysis (viewable using Powerport-E software). 
    • Minimum replacement time- Removable terminal blocks ideal in industrial environments. 
    • Front RS-232 port and Powerport-E software provides local computer access and user-friendly windows based interface for relay settings, configuration, and data retrieval. 
    • Breaker open/close from relay faceplate or remotely via communications. 
    • Fast an easy troubleshooting, improved maintenance procedures and increased device security. Provides detailed traceability for system configuration changes. 
    • Relays self-diagnostics and reporting improves uptime and troubleshooting. 
    • Breaker trip circuit monitoring improves the reliability of the breaker operation. 
    • Reduced relay to relay wiring and associated installation cost through high-speed inter-relay communications.
