Description
ZCT Zero Sequence Current Transformer
The ZCT zero sequence current transformer is an essential accessory for intelligent low-voltage switchgear systems equipped with earth fault or leakage current protection. When the device is configured with a leakage protection function, the ZCT transformer must be installed to enable accurate zero-sequence current detection and protection tripping.
