| Description | A range of moulded case Split core current transformers with in-built terminal covers. Primary ranges available up to 5000A with 5A secondary as standard. |
| Application | The Hobut range of Split-core current transformers has been designed to meet the growing demand for installation into existing networks. The split-core allows installation without disconnecting cables or busbar circuits. The products are ideal for retro-fitting and are therefore popular in the Energy Management and Power Factor Correction Industries |

Design |
| The 80 series Split-Core Current Transformers are of moulded case |
| construction, supplied complete with in-built terminal cover. |
|
Accuracy / Burden |
| Each Split-Core Current Transformer is supplied for use with various |
| class and accuracy burdens. For example, Type CTS80-1,400/5 is |
| suitable for: |
| 0.5% accuracy up to 2.5VA |
| 1% accuracy up to 6VA |
| 3% accuracy up to 10VA |
|
Order Example |
| A split-core Transformer Type CTS80-1 with a ratio of 400/5 is: |
| CTS80-1, 400/5. There is no reason to specify accuracy or VA |
| on your order for reasons outlined above. |
