CTSB0812 Split Core Current Transformer

Split-core current transformer

CTSB Split-Core Current Transformers – Designed for fast and easy installation on large primary conductors/ substation BUS bars. The split-core design permits non-contact AC current measurements without requiring that the primary conductor be taken offline and disconnected for CT installation.
