^ Complete range of current 52 models from 1 A to 10 kA GUIDE TO CHOOSE A CT To choose the CT properly you need to know: - System rated current This is used to determine the transformer's primary current, e.g.: System rated current: 425A = CT 500/5A - Power bar/cabte size This makes it possible to choose a CT with a window that is large enough to pass the phase bar/ cord through, the tendency is always to choose a slightly bigger window so as to have a tittle play that is useful during installation, e.g.: Cord of 120mm2 (max. outer diam. 21.5mm) = I choose model TA327 with 027mm hole.

CT with cable/ passing bar (Primary currents: 40...8000A) CT with primary winding (Primary currents: 5...600A) Open core CT (Primary currents: 60...5000A) Power absorbed (VA) by the cables connecting the CT and the instrument * The VA absorbed by the connection cables rises 4% for every 10% variation in the temperature. - Measurement class Classes 0.5/1 recommended for measuring power, electricity and cos^ Class 3 to be used for current measures on ammeters only - Performance (VA) This represents the maximum load that can be connected to the secondary terminals of the CT. The load consists of...
