SCT0121 Coil CT for primary currents 1…30 A, accuracy class 0,5

SCT0121 | Coil CT for primary currents 1…30 A, accuracy class 0,5

In order to guarantee power transmission, CTs need a correspondingly large measuring core volume with decreasing primary rated currents. The dimensions of standard CTs would quickly hit their limits on the basis of this physical principle. The SCT0121 coil CT with electrical isolation is specially designed for these low primary rated currents and is used in corresponding

applications.
