| Introduction: | | It is a 1 Phase Earth Fault Relay. It is best suitable for monitoring Earth Fault Current conditions for Motor / Pump loads. It is used in single phase system supply, where Under / Over Current monitoring or protection is required. It can be Rail mounted & have individually settable under / over current settings, thus increasing their utility as entire System Protection Relays. Added facility of adjustable Trip Time Delay and Power-ON Delay has also be provided, alongwith separate indications. |
