Ideal For
Not Recommended For
Connect primary conductor through the split-core. Secondary terminals: 1S1 and 1S2 for metering winding; if dual-winding, protection winding uses 2S1 and 2S2. Never open-circuit the secondary of a CT while energized - hazardous voltage. Ground the secondary winding at one point. Follow IEC 61869-2 and GB/T 20840.2 terminal markings.
