Protection Current Transformers

Protective CT’s are generally used in the switchgear industry for the protection of overhead lines or AC busbars.

TMC produce a range of Toroidal CT’s from 20mA to 5000A fault current. These are generally manufactured to BS EN 60044-1 with an accuracy class of 2.5% or 5%. We can also produce ‘E’ core laminated CT’s for use with 8/ 11pin relays.
