The Carlo Gavazzi DPA51 Series monitoring relay is a three-phase monitoring relay used for detection of incorrect phase sequence and total or partial phase loss with monitoring range up to 208 to 480VAC. The relay releases when one phase-phase voltage drops below 85% of the other phase-phase voltages or when the phase sequence is wrong.
