Phase asymmetry relays PS2DK are used for the protection of electric motors against asymmetries in the 3-phase mains without neutral and for monitoring the phase-sequence.

The switching-point is adjustable and can be adapted to the situation in the mains. If a motor, running with 2 phases, creates the 3rd phase, the sensitivity can be increased. With mains with high harmonics it can be necessary to reduce the sensitivity.

When the sensitivity is reduced to minimum (25% = potentiometer turned fully right) , the device works as a phase-sequence relay. It trips only at wrong phasesequence or missing phase.

If there is a wrong phase-sequence when switching on the device, the relay does not pick up.

  • Monitoring of phase-asymmetry
  • Monitoring of phase-sequence
  • Adjustable sensitivity 5…25 %
  • Output-relay with 2 change-over contacts
  • Switching delay adjustable 0,1 … 5 s
  • LED for display state of operation
