Split-Core current transformer

Due to their compact design and easy installation, split-core current transformers are particularly suited to applications involving places hard to access and limited in space. The separable cores also facilitate the installation on cables or bus bars.
  • Split-Core current transformer

Wherever an interruption of the current path is problematic or a measuring device has to be retrofitted in an uncomplicated manner, split-core current transformers are the correct choice. They transform primary rated currents into galvanically isolated secondary currents of 5 A or 1 A that can be used by the measuring system. The secondary side (usually a measuring device, display or control) is connected by terminals. The design ensures the safe assembly of the primary cable or bus bar in the current transformer which is confirmed by a clearly audible «clicking sound». An additional locking mechanism prevents accidental opening of the separable cores.
