DPA53CM23 Carlo Gavazzi

DPA53CM23, Control Relays and Protection Three-Phase Control and Phase Loss Model DPA53, DPA53CM23, 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 WLA and from 380 to 480 WLVs covered by two multi-voltage relays. For DIN rail mounting. 17.5mm case suitable for panel mounting., DPA53CM23, This relay measures its own 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.
