Output Specifications
DPA 01 C M44
3-phase relay for detection of
incorrect phase sequence,
total and partial phase loss.
Supply range from 208 to 690
VAC 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).

DPA01, PPA01
Mode of Operation
DPA01 and PPA01 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.
