Monitoring Relays
True RMS 3-Phase, 3-Phase+N, Multi-function
Types DPB01, PPB01
• TRMS 3-phase over and under voltage,
phase sequence and phase loss monitoring relays
• Detect when all 3 phases are present and have the correct phase sequence (except for N versions)
• Available versions (W4) supplied between phase and neutral
• Detect if all the 3-phase-phase or phase-neutral volt- ages are within the set limits
• Upper and lower limits separately adjustable
• Measure their own power supply
• Selection of measuring range by DIP-switches
• Adjustable voltage on relative scale
• Adjustable delay function (0.1 to 30 s)
• Output: 8 A SPDT relay N.E.
• For mounting on DIN-rail in accordance with
DIN/EN 50 022 (DPB01) or plug-in module (PPB01)
• 22.5 mm Euronorm housing (DPB01)
or 36 mm plug-in module (PPB01)
• LED indication for relay, alarm and power supply ON
