Split Core Current Transformer

Split-core current transformers are designed to meet the growing demand of installation into existing networks. Our Split Core (open-able) CTs can be a savings overall in the labor cost savings.Simply clip these around the wires being read. Secure them in place with a zip tie, without disconnecting cables or busbar circuits.

  • Product Detail

Key Properties:

  • Inherit the simple structure of the traditional C cores
  • Clamp-on core design, safer, easier installation, portable, don’t need to cut of the grid-power when adjust the inductance.
  • Comparing other materials, with high accuracy, due to nanocrystalline high permeability.
  • Energy conservation & environment protection, huge potential market.
