DPA03CM48 Carlo Gavazzi

DPA03CM48, Control Relays and Protection Three-Phase Sequence Control and Phase Loss Models DPA03, PPA03, DPA03CM48, Three-phase control relay for phase sequence detection and phase loss. With the potentiometer on the front panel, the minimum voltage level of the equipment is selected. Supply voltage scales from 208 to 240 WL, 380 to 480 WL and 600 to 690 WLAs covered by 3 multi-voltage relays. For DIN rail mounting or plug-in module, DPA03CM48, DPA03 and PPA03 measure their own three-phase supply voltage. The relay connects when all three phases are present, the phase sequence is correct, and each of the phase-phase voltages is above the adjusted minimum level. The relay disconnects when one of the phase-phase voltages is below the adjusted minimum level or when the phase sequence is incorrect. Example 1 The relay controls whether the feed has a correct sequence of phases and whether all 3 phases are present. Example 2 The relay disconnects when the voltage is interrupted in one of the phases, provided that the regenerated voltage does not exceed the selected minimum voltage level.
