Ideal For
Not Recommended For
connect primary through the inner diameter; secondary terminals are 1S1/1S2 for main winding, and 2S1/2S2 for protection winding if present. Never open-circuit the secondary of a CT while energized - hazardous voltage. Ground the secondary circuit at one point only. Follow IEC 61869-2 terminal markings.
