Parameter Specification Product Series EMR6 Brand Eaton Product Type Electronic Motor Protection Relay Main Circuit Voltage Up to 690V AC Motor Current Sensing Via external Current Transformers (CTs). The rating depends on the CTs used (e.g., for a 500A motor, 500:5A CTs would be used). Control Supply Voltage (D) 24-48V DC (Standard for "D" designation) or 100-240V AC/DC (depending on variant). Must be confirmed with datasheet. Protection Functions - Overload (Thermal replica) - Short-Circuit (Instantaneous) - Phase Unbalance / Loss - Locked Rotor / Jam - Undercurrent / Load Loss - Earth Fault (Ground Fault) - Tachometer Overspeed/Underspeed (if equipped with speed sensing) Control Functions - Start/Stop Control - Two-Wire / Three-Wire Control - Auto-Restart - Communication Capabilities Output Relays Typically 2 or 3 changeover relays for Fault, Warning, and General Control. Communication Common options: Modbus RTU, Profibus DP, or DeviceNet (highly dependent on the exact variant). Display & Interface LCD or LED display for setpoints, actual values, and fault messages. Mounting DIN Rail Mounting (35mm) Standards IEC/EN 60947-4-1, IEC/EN 60947-5-1
