Carlo Gavazzi Monitoring Relay Voltage 3-Phase Din-Rail DPB71CM23

Carlo Gavazzi Monitoring Relay True RMS 3-Phase, 3-Phase+N, Multifunction, DIN-Rail, SPDT, Supply: 208-240VAC.

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
