Over Current Relays

TE 530 series of over current relays are ideal for sensing over current faults in any or all phases for protection of AC machines, transformers, generators etc. The relay monitors the current passing in any feeder secondary. The resultant current is digitally compared to the settable reference. Each phase has its independent setting. Timer starts on trip condition and is common for all three phases - a changeover occurs. Time must be set according to the system requirements. Two sets of changeover contact are available - common for all.
