Descrizione del prodotto

The undervoltage relays IL 9071 and SL 9071 of the VARIMETER series monitor undervoltage, phase failure, asymmetry and missing neutral conductor in three-phase or single-phase networks. The measurement is very simple and without extensive wiring, as no separate auxiliary supply is necessary. The early detection of up-coming break downs and preventive maintenance avoid expensive damages. As user you profit from the reliability and availability of your plant.
