The new 3UG4 line monitoring relays permit a maximum degree of protection to be achieved for machines, plants and systems. This means that line and voltage faults can be detected early on and the appropriate response is initiated before far more significant subsequent damage can occur.. Thanks to the wide voltage range, it can be used on all line supplies around the world – from 160 V to 690 V – without an auxiliary voltage. Can be variably set to above range, below range or window monitorin

The ATC Diversified SLA Series is designed to protect 3-phase equipment against Phase Loss, Under Voltage, and Phase Reversal conditions. With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (Pick-Up). When incorrect phase sequence or phase loss occurs or the three-phase voltages fall below the drop out voltages, the relay will de-energize (Drop-Out). On models featuring indicators, the LED glows when all line conditions are normal. Both Delta and W
