DPA55CM44 Carlo Gavazzi

DPA55CM44, Control and Protection Relays Three-phase voltage selection Model DPA55, DPA55CM44, Three-phase relay for detection of incorrect mains voltage. Also for phase sequence detection and phase loss. This equipment allows you to disconnect the incorrect supply voltage when it is different from the desired one. Supply voltage scale from 208 to 480 WL plus the selection of the various possible rated voltages. For DIN rail mounting. 17.5 mm box suitable for panel mounting., DPA55CM44, This equipment measures its own three-phase supply voltage. The relay connects when all phases are present, the phase sequence is correct, and each of the phase-phase voltages is within the desired tolerance (± 10% or ± 15%). Example 1 The relay checks whether the power is correct for the required equipment. Example 2 The relay disconnects when the phase sequence is not correct or when the voltage is outside the selected limits.
