The Carlo Gavazzi DPA55 monitoring relay is a three-phase monitoring relay used for detection of incorrect phase sequence, and total or partial phase loss while also detecting if the voltage is at a desired level (±10% or ±15%) as set by the user. The monitoring range of 380 to 480 VAC is covered by two multi-voltage relays. The relay operates when all the phases are present, the phase sequence is correct and each phase-phase voltage is within the desired tolerance. The relay releases when one phase-phase voltage drops below the setpoint or when the phase sequence is incorrect. The DPA55 is DIN-rail mountable, and the 17.5mm housing is suitable for either back or front panel mounting.
