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)
