3-Phase Sequence and Phase Loss

ꢀ

Type DPA53

ꢀ

Product Description

3-Phase monitoring relay for detection of incorrect phase

sequence and phase loss. Using the front knob it can be decided

the undervoltage setpoint of the unit.

Supply range from 208 to 240VAC or 380 to 480VAC covered by

two multivoltage relays. For mounting on DIN-rail.

Housing 17.5mm wide suitable both for back and front panel

mounting.

Property

• Knob-adjustable undevoltage detection

• Measures its own power supply

• Power supply range: 208 to 240 and 380 to 480 VAC

• Output: 1 A SPDT relay normally energized

(±±15%

• For mounting on DIN-rail in accordance with

• ±7.1 mm DIN-rail housing (DIN 43880%

DIN/EN 10 022

• LED indication for relay and power supply ON

sequence and phase loss

• 3-phase monitoring relay for phase

• Detects all phases are present and have the correct sequence
