Earth Fault Relay-ACAG11, ACAG12

These are attracted armature type instantaneous acting relays. Because of their High reliability, these are used for all kinds of control circuits in power stations and other installations. Operation of these relays is satisfactory even after long periods of idleness.

These relays are widely used for Earth Fault protection of A.C. Systems specially where earth resistance is not sufficiently low to trip the main ACB. These Relays fully conform to IS 3231-1965 and are type tested at National Test House, Alipore, Calcutta and found to comply with ISS-3231-1965 vide test certificate No. E/Misc./89/14 dt. 4.7.89.

ACAG11 – Fixed setting 10% or 20%
ACAG12 – Setting 10% to 40% or 20% to 80% in 7 step
Contact – 2 NO or 1 NO + 1 NC with flag (Hand Reset).

ACAG11 - 105W x 115H x 130D mm (93 x 104mm cutout)
ACAG12 - 125W x 155H x 145D mm (116 x 145mm cutout)
