Motor Relay (EMR 3000 or 4000 or 5000)

Eaton Motor Relay (EMR 3000 / 4000 / 5000) Eaton’s EMR motor protection relay is a multifunctional microprocessor-based protective relay for the protection of any size motor at all voltage levels. It is most commonly applied on medium voltage or larger motors. The EMR relay is a current and voltage device with built in differential protection that provides complete and reliable motor protection, monitoring, diagnostics, metering, and starting control functions.

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.
• Embedded IEC61850 protocol with GOOSE messaging capabilities
