Three-Phase

• It is intended for monitoring the current in 3-phase devices (e.g. cranes, motors, etc.).
• 24 – 240 V AC/DC power supply, galvanically separated from the circuit of the monitored current.
• Adjustable delay level (when exceeding the preset limit).
• Adjustable function:
  • UNDER – monitors the drop in the strength of current below the preset value (I)
  • OVER – exceeding the preset value (I).
    Option of connecting via the current transformers to increase the value of the monitored current.
