New Original Schneider EOCR-I3DM-WRDUWZ Digital Motor Protector Relay<\/h1>\n

1. Product Overview<\/h2>\n

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\u2013240 V AC\/DC, with an internal measurable current range of 0.5\u201380 A for definite time protection and 0.5\u201332 A for inverse time protection.<\/p>\n

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.<\/p>\n

2. Main Functions<\/h2>\n
    \n
  1. Full-range Motor Fault Protection<\/strong> Covers overcurrent, undercurrent, phase loss, phase reversal, current unbalance, motor stall and locked rotor protection.<\/li>\n
  2. Selectable Tripping Characteristics<\/strong> Supports definite time, inverse time and thermal inverse time curves to match different motor thermal load requirements.<\/li>\n
  3. Digital Real-time Monitoring & Fault Recording<\/strong> Cyclic display of three-phase operating currents; stores the latest three fault records including fault type and current value.<\/li>\n
  4. Modbus RTU RS485 Communication<\/strong> Upload operating data, fault information and receive parameter settings remotely for PLC and SCADA system integration.<\/li>\n
  5. Dual Output Contact Configuration<\/strong> OL trip contact (1NO+1NC) and AL alarm contact (1NO) to separate pre-alarm and emergency shutdown logic.<\/li>\n
  6. Multiple Reset Modes<\/strong> Supports manual local reset, electrical remote reset and automatic reset configurable according to site demands.<\/li>\n
  7. Operation Hour Accumulation<\/strong> Records total motor running time to facilitate maintenance scheduling and equipment lifecycle management.<\/li>\n<\/ol>\n
