Product Details

Line Supply and Three Phase Voltage

3UG4 relays that monitor current, power factor and active current are ideal for monitoring the load of motors and functionality of electronic loads. These devices detect the effect of wear and faults early on. This means that appropriate actions can be taken before more significant damage occurs.

Wide voltage range versions reduce inventory stock levels
Variable settings for over-range, under-voltage or window monitoring
Delay times and reset switch
Actual value and fault types are permanently displayed
Removable terminals
22.5mm wide
3UG4614 to 3UG4617 can be digitally set, with fault memory and LDC display
