Relays for mining

Insulation condition control relay UKI/24

Control system insulation type UKI/24 is designed to monitoring the insulation resistance of the receiver for example switchgears, motors without voltage. The relay cooperates with diode star unit. The relay is designed for use in 3-phase mains voltage of 230V, 400V, 500V with insulated neutral point of the transformer. In cooperation with the main contactor provides the blocking of apply the voltage to the controlled section of the grid by lowering insulation resistance under 25k ± 20%.
