The Carlo Gavazzi DPA53 monitoring relay is a three-phase monitoring relay used for detection of incorrect phase sequence, and total or partial phase loss. The monitoring range of 380 to 480 VAC is covered by two multi-voltage relays. The proper undervoltage level can be set according to the phase-phase voltage and the desired sensitivity. The relay operates when all the phases are present, the phase sequence is correct and each phase-phase voltage is above the adjusted setpoint. The relay releases when one phase-phase voltage drops below the setpoint or when the phase sequence is incorrect. The DPA53 is DIN-rail mountable, and the 17.5mm housing is suitable for either back or front panel mounting.
