Introduction:
Three phase or three phase with neutral line voltage monitoring relay for phase sequence, phase loss, over and under voltage
 with built in time delay function.Supply ranges from 208 to 480 VAC covered by one multivoltage relay.
17.5 mm wide housing suitable both for back and front panel mounting.

Property:
TRMS  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 its own power supply
Adjustable voltage on relative scale
Adjustable delay function
Output: 5 A SPDT relay 
for mounting on DIN rail in accordance with DIN EN 50 022
17.5 mm DIN rail housing
LED indication for relay, alarm and power supply ON
