TA_R Split - core transformers
The current transformer TA__R is an open core transformer for measuring instrumentation. It is a transformer for through primary, for cable or PCB of different dimensions. Its enclosure is made of resin. Its main advantage is the ease of installation due to the possibility of opening the core. It is a more robust transformer because it is covered in resin, allowing it to be installed even outdoors.
