Supply voltage and three-phase voltage. 3UG4 relays for monitoring current, power factor, and active power, ideal for monitoring motor loads and the operation of electronic loads. These components detect the effects of wear and failures in advance, allowing appropriate measures to be taken before serious damage occurs. Versions with a wide voltage range reduce the need for spare parts. Variably adjustable monitoring for overvoltage and undervoltage or window monitoring. Delay times and reset buttons. Actual values and error types are permanently displayed. Removable connections, 22.5 mm wide. 3UG4614 to 3UG4617 can be digitally set, with error memory and LCD display, 1-20 V hysteresis. Phase loss (except order number 518-7275).
