Monitoring Relays

Product Description

?3-phase monitoring relays for phase sequence and phase loss

?Detect when all 3 phases are present and have the correct sequence

?Measure on own power supply

?Power supply range: 208 to 690 VAC (+10 -15%)

?Output: 8 A SPDT relay or 8 A DPDT normally energized ?For mounting on DIN-rail in accordance with DIN/EN 50 022 (DPA01) or plug-in module (PPA01)

?22.5 mm Euronorm housing (DPA01) or 36 mm plug-in module (PPA01)

?LED indication for relay and power supply ON

3-Phase Sequence and Phase Loss Types DPA01, PPA01

Input Specifications

Output Specifications

3-phase relay for detection of incorrect phase sequence,total and partial phase loss.Supply range from 208 to 690VAC covered by two multi-voltage relays.

For mounting on DIN-rail or plug-in module. The device detects regenerated voltages up to 85% of the nominal voltage (phase-phase).

Mode of Operation

DPA01 and P P A01 monitor their own 3-phase power supply. The relay operates when all the phases are pre-sent and the phase sequence is correct. The relay releases when one

phase-phase voltage drops below 85% of the other phase-phase voltages.

Example 1

The relay monitors that the power supply has the correct phase sequence and that all phase voltages 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.
