Przekaźniki ochronne i urządzenia wczesnego ostrzegania

Eaton’s Motor Relays (EMR3MP0, EMR3000, EMR4000 and EMR5000) 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.

Flexible configuration options and multiple settings groups

The EMR-3000 is a current-only motor relay with flexible configuration options and multiple settings groups.

The EMR-4000 has the same features as the EMR-3000 but adds voltage protection and metering.

The EMR-5000 builds on the EMR-4000 by adding motor differential protection and a larger display.

Improved coordination

Zone selective interlocking

Główne cechy

Use basic motor nameplate data to create a custom overload curve to accurately protect the motor. 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 USB port and Powerport-E software provides local computer access and user-friendly windows based interface for relay settings, configuration, and data retrieval.
Fast and 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.

Reliable protection for any size

Eaton’s E-Series microprocessor-based protective relays offer reliable, secure and complete protection and control of power generation and distribution systems. Motor relays specifically provide you complete and reliable motor protection for any size motor at different voltage levels.
