PRI-53:Three-phase relay

  • Intended for monitoring the current in three-phase devices (e.g. cranes, motors, etc.)
  • 24-240 V AC/DC power supply galvanically separated from the circuit of the monitored current
  • Adjustable current level in % of In:
  • Fixed difference level
  • 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
  • 2 types depending on the strength of rated current In (1A, 5A)
  • 6-MODULE, DIN rail mounting
  • Output relay with 2 changeover contacts
  • Option of connecting via the current transformers to increase the value of the monitored current by up to 600 A
