Eaton MP-3000 66D2032GX1 – Intelligent Motor Protection Relay

Comprehensive Motor Protection

The MP-3000 66D2032GX1 continuously monitors motor parameters such as current, voltage, power, and temperature. It provides protection against overload, phase unbalance, phase loss, locked rotor, ground fault, and undercurrent conditions. By detecting anomalies early, it prevents costly motor damage and unplanned downtime.

Key Features

• Accurate Measurement: True RMS current and voltage sensing ensures reliable protection even with distorted waveforms.

• User-Friendly Interface: Local display and keypad allow easy configuration, monitoring of real-time data, and viewing of trip event records.

• Multiple Communication Options: Supports Modbus RTU, Profibus DP, or DeviceNet (depending on variant) for seamless integration with PLC and SCADA systems.

• Flexible Control: Built-in relay outputs for trip, alarm, and control functions; digital inputs for remote reset or interlocking.

Technical Specifications (Model 66D2032GX1)

• Rated Current: Configurable via CT ratios, typically up to 10A direct or through external CTs.

• Supply Voltage: 100-240 V AC/DC or 24 V DC (check variant).

• Protection Functions: Thermal overload (I²t), phase imbalance, phase reversal, underload, ground fault, etc.

• Output Relays: 3 programmable output relays (Form C).

• Digital Inputs: 2 opto-isolated inputs.

• Communication: RS485 port with Modbus RTU protocol.

• Display: Backlit LCD showing current, voltage, trip cause, and settings.
