CARLO GAVAZZI Multi Funtion Three Phase Solid State Relay SSR

3-phase or 3-phase+neutral line 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.

General Characteristics

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

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

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

• Upper and lower limits separately adjustable

• Measures its own power supply

• Selection of measuring range by DIP-switches

• Adjustable voltage on relative scale

• Adjustable delay function (0.1 to 30 s)

• Output: 5 A SPDT relay N.E.

• 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
