SCT0121-0001 | Coil CT, 1 A AC, 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 SCT0xxxx coil CTs with electrical isolation are specially designed for these low primary rated currents and are used in corresponding applications.
