Monitoring Relays
3-Phase, Phase Sequence/Loss - Asymmetry
Types DPB02, PPB02
• 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)
