The CC 0.66 I Type series power current transformers adopt split core silicon steel or nanocrystalline cores, wound with pure copper enameled wire, and the white housing is made of high-quality PC or nylon engineering plastic. Equipped with multiple flexible installation methods (bracket fixing, pressure plate fixing, DIN rail mounting) and stable precision, they are suitable for various power transformation and monitoring applications with primary current 50A-2000A.
Primary current 50A-2000A, secondary current 5A/1A with complete specifications, meeting diverse current sampling needs
Multiple accuracy classes: 0.1, 0.2S, 0.2, 0.5S, 0.5, 1.0 class for different precision requirements
Three installation methods available: bracket fixing, pressure plate fixing and DIN rail mounting, highly adaptable to on-site conditions
All cores undergo high-temperature heat treatment under nitrogen protection, ensuring superior performance and stable precision
White heat resistant housing (120℃) with flame retardant grade V0/V1, lead-free process and RoHS2.0 compliance
