INFORMATION

Description

Resin-coated current transformer, busbar. Other characteristics:

  • From 75 to 5000 A
  • Inner diameter from 30 to 180 mm, according to type 
  • Secondary .../5 A ( .../1 A on request)

Applications

These transformers have been conceived to convert nominal currents in any installation to current values adjusted to measurement devices. Its synthetic resin increases its resistance to adverse environmental conditions.
