The 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. The wide voltage range versions reduce spare parts inventory requirements. They feature variable settings for overrange, undervoltage, or window monitoring, along with delay times and reset switches. Actual values and fault types are permanently displayed, and removable terminals are included. The 22.5 mm wide models 3UG4614 to 3UG4617 can be set digitally, with fault memory and LCD display, and a hysteresis of 1-20 V. Phase loss is monitored, except for specific order numbers.
