Short DescriptionUNDER/OVER VOLTAGE RELAY FOR 3PH 4-WIRE (PLUG-IN) 415V
Long DescriptionThe NUOV-ND monitors under and over voltage of 3 phase 4-wire mains. It will detect variations of the voltage in each phase independent of the voltages in the other two phases. The relay trips if the voltage of the monitored mains drops below or rises above the respective preset points. The NOV-ND has an adjustable tripping delay from 0-20 sec. There are 2 separate sets of contacts; one for under voltage (9-8-7) and one for over voltage (3-5-6) trip controls. There are also 2 green LEDs to indicate the under and over normal voltage conditions and 1 amber LEDs to indicate delay, then trip condition.
