CTSB Split Core Current Transformer

Split-core current transformer
Application:The CTSB series of split-core current transformers are used where it is desirable that the CT (current transformer) installation does not require the disruption of the primary conductor by taking the primary conductor offline and disconnecting for installation.
The robust packaging features tight fitting mating magnetic core halves, secure closure of the current transformer after installation, and hardware to secure the position of the primary conductor within the current transformer opening window. These features insures consistent and highly accurate AC current measurement performance over the life of the current transformer installation.
The robust CTSB split-core current transformer design, manufactured in an ISO9001 certified manufacturing facility, insures many years of defect free operation backed by a strong product warranty of 36 months
