CARLO GAVAZZI DPA51CM44

the 3-pHASE SEQUENCE AND PHASE LOSS MONITORING RELAY

Compact yet powerful.

3-Phase relay for detection of incorrect phase sequence, total and partial phase loss. Supply range from 208 to 480 VAC. For mounting on DIN rail. Housing 17.5 mm wide, SPDT relay output, suitable for back and front panel mounting. The device detects regenerated voltage up to 85% of the nominal voltage (phase-phase).

Mode of Operation

DPA51 monitors its own 3- phase power supply voltage. The relay operates when all the phases are present and the phase sequence is correct. The relay releases when one phase-phase voltage drops below 85% of the other phase-phase voltages

or when the phase sequence is wrong. Example 1 The relay monitors that the power supply has the correct phase sequence and that all phases are present.

Example 2 The relay releases in case of interruption of one or more phases, provided that the regenerated voltage does not exceed 85% of the phase-phase voltage.

CARLO GAVAZZI 3-Phase Sequence and Phase Loss Type DPA51.
