423-RV341

Voltage supervisor relay for protection of 3-phase equipment and instalations.

  • Modular box (3 modules) for application on DIN rail.
  • Button for minimum allowable voltage regulation (Vmin).
  • Indication of voltage lower than the minimum allowable, through red LED.
  • Button for maximum allowable voltage regulation (Vmax).
  • Indication of voltage higher than the maximum allowable, through red LED.
  • Button for regulation of time for delay on release (Toff).
  • Indication of Toff in countdown, through yellow LED.
  • Button for regulation of time for delay on operation (Ton).
  • Indication of Ton in countdown, through yellow LED.
  • Indication of tension level on each phase, through LEDs L1, L2 and L3 (green or red depending if they are in or out the pre-established limits).
  • Indication of phase sequence,through bi-color LED ( green=OK, red= exchange or lack/assimetry of phase).
  • Indication of output relay ON (17-18),through green LED.
  • Supply voltage indicated on the front of the relay.
