Webaccuracy classes. Depending on their Accuracy Class, CTs are divided into Metering Accuracy CTs or Relaying Accuracy CTs (Protection CTs). A CT can have ratings for both groups. Metering Accuracy CTs are rated for specified standard burdens and designed to be highly accurate from very low current to the maximum current rating of the CT. WebWe have developed a true Class 1 Panel Mount “ Plug and Play” solution by where our meters are Class C (0.5%) and the CTs are Class 0.5 (0.5%) giving an overall accuracy of 1%. We are also improving our DIN rail CT operated meters and will be all retested to class C to insure all our products and systems as a standard will conform to Class C.
