Monitoring Relays
True RMS 3-Phase, 3-Phase+N, Multi-function
Type DPB71
• 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 volt- ages 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
