Wound Primary Current Transformer

Wound primary current transformers are used wherever small primary rated currents of 1 A or more must be converted by the measuring system into usable, galvanically isolated secondary rated currents of 5 A or 1 A. In contrast to plug-in or Kabelumaustromwandler winding transformer have 4 screw terminals. The primary current as well as the secondary current is connected directly via screw terminals on the order and rear side.
