Monitoring Relays
True RMS 3-Phase, Phase Sequence/Loss - Asymmetry
Types DPB02, PPB02
DPB02
PPB02
⢠TRMS 3-phase phase sequence, phase loss and
asymmetry monitoring relays
⢠Detect when all 3 phases are present and have the
correct sequence
⢠Detect if asymmetry level is below the set value
⢠Measure on own power supply
⢠Selection of measuring range by DIP-switches
⢠Adjustable asymmetry on relative scale
⢠Adjustable delay function (0.1 to 30 s)
⢠Output: 8 A relay SPDT N.E.
⢠For mounting on DIN-rail in accordance with
DIN/EN 50 022 (DPB02) or plug-in module (PPB02)
⢠22.5 mm Euronorm housing (DPB02)
or 36 mm plug-in module (PPB02)
⢠LED indication for relay, alarm and power supply ON
