Buy 150/1 A protection current transformers – questions
What does 5P10 mean?
"5P" means at most 5 % composite error, "10" is the accuracy limit factor: up to 10 times rated current the CT stays within this limit so the relay trips reliably. Available for 150/1 A: 5P5, 5P10, 10P5 and 10P10. Protection CTs in the guide →
Does it fit my conductor?
The aperture decides. The types in this list take round conductors of Ø 23–30 mm, depending on the version; busbar sizes are in the datasheet of each type. CT finder →
