Can any one help me how to set an overload set the range from 2.8A to
4A , rated motor current 22A, CT 60/5A
Answer Posted / thirumoorthy s
the CT ratio is for metering only. so we cant set the O/L
setting for ur (2.8-4)A relay. u should provide correct O/L
relay. ie (18-25)A. the rated rating 22A, So we can set it
ion 20A.
