Rish Relay - AR
Rish Relay - AR monitors AC current of a system/equipment and protects it from overcurrent, undercurrent and current unbalance. As well as it indicates the occurrence of faults with help of LED indications. It is a potentiometer based relay thus it is easy to programme trip points and time delays
Rish Relay 252-PAx - AC Current Relay
The AC Current provides continuous surveillance of the monitored circuit. When the measured current moves outside the set point limit, the relay will operate. An adjustable time delay is provided to prevent the relay from tripping for a predetermined period to prevent nuisance tripping.
