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.
