Dold RN9854.11 AC150-528V 4-20% 0-30S, Voltage Relay, sku: 0069301

The measuring relays RL 9854 and RN 9854 of the VARIMETER series monitors overvoltage, undervoltage and voltage range in single-phase systems. The measurement is very simple and without extensive wiring as there is no auxiliary power supply necessary. The monitoring functions are easily selectable using a single turn switch without complex menu structure. 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.
