CTSB0508 Split Core Current Transformer

Split-core current transformer

The CTSB0508 series are designed for monitoring the AC current carried by large primary conductors or substation BUS bars. The split-core current transformers can be installed without disconnecting the primary current conductor. The CTSB features hardware to firmly secure the current transformer halves and to secure the current transformer to the primary conductor/ BUS bar.
