Ground Fault Protection Relay

EOCR-DZ(T) Electronic Ground Fault Relay is helpful in monitoring the fault current within the grounded AC systems that possess high resistance. It work for both single and three phase systems and is also capable of using three separate time delays such as trip, start up  and release delay. All the settings can be easily changed with the help of easy to use menu.
