Short description:
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 100 A (primary side) and 1 A (secondary side)
  • No measuring cable interruption
  • Ideal for use in very confined spaces
  • Rapid mounting
  • For use around insulated cables up to 18 mm diameter
  • Compact and hinged
  • Color-coded connecting cable 3 m
