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