Monitoring Relays
3-Phase Voltage selection
Type DPA55
• 3-phase monitoring relay for phase
sequence
• Detects if voltage is at the desired level (± 10% or ±15%)
• Measures own power supply
• Wide power supply range: 208 to 480 VAC (±15%)
• Output: 5 A SPDT relay normally energized
• For mounting on DIN-rail in accordance with
DIN/EN 50 022
• 17.5 mm DIN-rail housing (DIN 43880)
• LED indication for relay and power supply ON
Product Description
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 volt-
age 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.
