DPA01CM44 Carlo Gavazzi

DPA01CM44, Control Relays and Protection Three-Phase Sequence Control and Phase Breakage Models DPA01, PPA01, DPA01CM44, Sequence Control Relays and Total or Partial Phase Breakage for Three-Phase Systems. With measurement scale from 208 to 690 WLA, covered by 2 multi-voltage relays. For mounting on DIN rail or plug-in module. The relay makes it possible to detect regenerated voltages of up to 85% of the nominal voltage (phase-phase)., DPA01CM44, The DPA01 and PPA01 devices measure their own three-phase supply voltage. The relay connects when all phases are present and the phase sequence is correct. The relay disconnects when one of the phase-phase voltages falls below 85% of the other phase-phase voltages. Example 1 The relay controls the supply voltage so that the phase sequence is correct and the voltages are present in the 3 phases. Example 2 The relay disconnects when one of the phases is interrupted when the regenerated voltage does not exceed 85% of the phase-phase voltage of the network.
