WAGO current transformer


WAGO’s compact split-core current transformers are ideal for retrofitting existing systems. They are perfect for applications in which the current path must not be disrupted. The transformer’s accuracy permits extremely precise current measurements. The split-core current transformers are capable of supplying the specified rated power at the end of the secondary cable. All transformers are supplied with color-coded cables. Two UV-resistant cable ties are also included for secure and easy mounting.


  • Current ratios from 60 A up to 1000 A (primary side) and 1 A or 5 A (secondary side)
  • No measuring cable interruption
  • Ideal for use in very confined spaces
  • Rapid mounting
  • For use around insulated cables up to 42 mm diameter
  • Compact and hinged
  • Color-coded connecting cables up to 5 m
