3-phase or 3-phase+neutral line voltage monitoring relay for phase sequence, phase loss, asymmetry, tolerance, 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.

Features

• TRMS 3-phase over and under voltage, phase sequence, phase loss, asymmetry and tolerance monitoring relay

• Detect when all 3 phases are present and have the correct sequence

• Detect if all the 3-phase-phase or phase-neutral voltages are within the set limits

• Detect if asymmetry and tolerance are within the set value

• Separately adjustable setpoints

• Separately adjustable delay functions (0.1 to 30 s)

• Output: 2 x 5 A relay SPDT NE

• For mounting on DIN-rail in accordance with DIN/EN/ EC 60715

• 35.5 mm Euronorm housing

• LED indication for relays, alarm and power supply ON
