Application Scenarios:

  • Industrial automation systems for motor-driven equipment protection
  • Manufacturing line motor control and monitoring
  • Power plant auxiliary motor protection
  • Pump, fan, and compressor motor management
  • Process industry motor protection requiring remote diagnostics

Performance Parameters:

  • 120 A rated current for medium-voltage motor applications
  • Fast response to fault conditions to protect motors and connected equipment
  • High reliability for continuous operation in industrial settings
  • Configurable protection parameters to suit different motor characteristics

Material and Structural Characteristics:

  • Industrial-grade enclosure with integrated display panel
  • Robust terminal blocks for power and control wiring
  • PCB with conformal coating for environmental protection
  • Compact form factor for panel or switchgear mounting

Working Principle: The module continuously monitors motor current, voltage, temperature, and other parameters. When measured values exceed configured thresholds, the module initiates protective actions such as tripping the motor contactor or issuing alarms. It communicates status, measurement data, and event records to supervisory systems via Modbus, Profibus, or Ethernet/IP. Installation Requirements:

  • Mount in a motor control center or protection panel
  • Connect three-phase current and voltage inputs via CTs and PTs
  • Wire control power (24 V DC) and communication cables
  • Configure protection parameters and communication addresses

Usage Notes:

  • Verify CT and PT ratios match the module configuration
  • Set protection curves and thresholds according to motor nameplate data
  • Test all protection functions during commissioning
  • Periodically verify communication links with the supervisory system
