Nippen earth leakage relay model has a high performance microcontroller based 3 digit 7 segment led display. It detects leakage cuurent well before it crosses threshold limits and isolates the supply instantly with the help of MCCB/ACB/OCB and contactor. The unit of ELR consists of two parts, a) Basic relay b) Core balance current transformer(CBCT). Nippen ELRs have the unique feature of a led display. we provide 2 model of relay - Din rail and panel mountable.
