Digital Electronic Overcurrent Relay
Product Code : 8S0A2820
Product Description

Our offered Digital Electronic Overcurrent Relay is one of the simplest ways for protecting the line from over current. It owes its usage during an elevation in the current that will also result in the increase of the load. Be it instantaneous, time or inverse time over-current relays, we offer all the kinds, depending upon the requirement.
