Introduction:
Three phase line voltage monitoring relay for phase sequence, phase loss, asymmetry,
Tolerance,over and under voltage with built in time delay function.  Supply ranges from 208 to 480 VAC
Covered by two multivoltage relays.

Property:
TRMS  three phase over and under voltage, phase sequence, phase loss, asymmetry and tolerance monitoring relay
Detect when all three phases are present and have the correct sequence
Detect if all the three phase to phase or phase to neutral voltages are within the set limits
Detect if asymmetry and tolerance are within the set value
Separately adjustable setpoints
Separately adjustable delay functions  
Output: 5A relay DPDT NE
for mounting on DIN rail in accordance with DIN EN 50 022 
35.5 mm Euronorm housing 
LED indication for relays, alarm and power supply ON
