Supply voltage and three-phase voltage. 3UG4 relays for monitoring current, power factor, and active current are ideal for monitoring motor loads and the operation of electronic loads. These components detect the effects of wear and failures in advance, allowing appropriate action to be taken before serious damage occurs. Wide voltage range versions reduce spare parts inventory requirements. Variable settings for overrange, undervoltage, or window monitoring. Delay times and reset switches. Actual value and fault types are permanently displayed. Removable terminals 22.5 mm wide. 3UG4614 to 3UG4617 can be set digitally, with fault memory and LCD display. 1-20 V hysteresis. Phase loss (except order no. 518-7275).
