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 phase sequence or missing phase.
If there is a wrong phase-sequence when switching on the device, the relay does not pick up.
Changes from P222505 to P227105: Version with spring terminals RoHS/REACH compliant
