Product Description Ordering Key
3-Phase relay for detection of
incorrect mains voltage. Also
detecting incorrect phase
sequence and phase loss.
This unit allows to stop
incorrect power supply voltage when different from the
desired one.
Power supply range from 208
to 480 VAC plus selection of
the different possible nominal
voltages. For mounting on
DIN-rail. Housing 17.5 mm
wide suitable both for back
and front panel mounting.

Mode of Operation
DPA55 monitors its own
3- phase power supply.
The relay operates when all
the phases are present, the
phase sequence is correct
and each phase-phase voltage is within the desired tolerance (± 10% or ± 15%).
