The Ritherdon CT Chamber is used to house a meter and current transformers in a tamper-proof, sealable unit. It is designed for 100A to 600A supplies (70kVA to 430kVA) and permits flexible installation (e.g. can accommodate supply from top or bottom).

The Enclosure is supplied separately to the back plate and can be easily secured inside the unit once mounted onto the cut-out and fixed to the wall. The individual covers which protect the electrician allow work to be carried out in the CT Chamber on one phase without having to isolate the complete unit.
