The Over- and Undervoltage relays IL 9077/800 and SL 9077/800 of the VARIMETER PRO series monitor overvoltage, undervoltage and Phase failure in three-phase or single-phase networks. The measurement is 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.
