New Original Schneider EOCR-I3DM-WRDUWZ Digital Motor Protector Relay
1. Product Overview
EOCR-I3DM-WRDUWZ is an original Schneider Electric multifunctional digital motor protection relay belonging to the EOCR intelligent protection series. This window-through type unit integrates built-in three current transformers, a digital display panel and RS485 Modbus RTU communication function. The control power supply supports 100–240 V AC/DC, with an internal measurable current range of 0.5–80 A for definite time protection and 0.5–32 A for inverse time protection.
It provides comprehensive monitoring and protection for three-phase AC motors, widely adopted in water treatment equipment, conveyor systems, pump units, fan systems, packaging machinery and automated production lines. The digital screen displays real-time three-phase current, fault codes and operation records, supporting remote data access and equipment management via communication bus.
2. Main Functions
- Full-range Motor Fault Protection Covers overcurrent, undercurrent, phase loss, phase reversal, current unbalance, motor stall and locked rotor protection.
- Selectable Tripping Characteristics Supports definite time, inverse time and thermal inverse time curves to match different motor thermal load requirements.
- Digital Real-time Monitoring & Fault Recording Cyclic display of three-phase operating currents; stores the latest three fault records including fault type and current value.
- Modbus RTU RS485 Communication Upload operating data, fault information and receive parameter settings remotely for PLC and SCADA system integration.
- Dual Output Contact Configuration OL trip contact (1NO+1NC) and AL alarm contact (1NO) to separate pre-alarm and emergency shutdown logic.
- Multiple Reset Modes Supports manual local reset, electrical remote reset and automatic reset configurable according to site demands.
- Operation Hour Accumulation Records total motor running time to facilitate maintenance scheduling and equipment lifecycle management.
