CTSB0812 Split Core Current Transformer

Split-core current transformer

The CTSB series of split-core current transformers are designed for the measurement of AC currents carried by large primary conductors or substation BUS bars.The split-core design permits the fast and easy installation on large primary conductors/ substation BUS bars without requiring that the primary conductor be taken offline and disconnected for CT (current transformer) installation.
The CTSB series of split-core current transformers feature a high performance magnetic core for highly accurate AC current measurement. The robust packaging features;

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.
