Introduction:
Three phase voltage monitoring relay for phase sequence, phase loss, over and under voltage
(separately adjustable set points) with built in time delay function. Supply ranges from 208 to 480 VAC covered by
Two multivoltage relays. 35.5 mm wide housing suitable both for back and front panel mounting.

Property:
Three phase over and under voltage, phase sequence and phase loss monitoring relay
Detects when all three phases are present and have the correct phase sequence
Detects if all the  three phase to phase or phase to neutral voltages are within the set limits
Upper and lower limits separately adjustable
Measures on own power supply
Selection of measuring range by DIP switches
Adjustable voltage on relative scale
Output: 5 A SPDT relay NE
for mounting on DIN rail in accordance with DIN EN 50 022
35.5 mm DIN rail housing
LED indication for relay, alarm and power supply ON
