Supply voltage and three-phase voltage. 3UG4 relays are designed for monitoring current, power factor, and active current, making them 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 are available for overrange, undervoltage, or window monitoring. Delay times and reset switches are included, with actual values and fault types permanently displayed. Removable terminals are 22.5 mm wide. Models 3UG4614 to 3UG4617 can be set digitally, with fault memory and LDC display, featuring a hysteresis of 1-20 V for phase loss.
