The Carlo Gavazzi DPB01 monitoring relay is a three-phase monitoring relay used for phase sequence detection, phase loss and asymmetry with built-in time delay function. The monitoring range of 380 to 480 VAC is covered by two multi-voltage relays. The DPB01 operates when all three phases are present at the same time, the phase sequence is correct and the phase-phase voltage levels are within set limits
