The CC 0.66 II Type series power current transformers are designed with split core silicon steel or nanocrystalline cores, wound with pure copper enameled wire, and the light blue housing is made of PC or nylon engineering plastic. With a wide primary current range (50A-8000A), multiple accuracy classes and reliable fixation (bracket/pressure plate fixing), they are ideal for high-precision AC input current sampling of primary power supply in power transformation and monitoring projects.
Primary current 50A-8000A, secondary current 5A/1A/0.1A with complete specifications for high current applications
Multiple accuracy classes: 0.1, 0.2S, 0.2, 0.5S, 0.5, 1.0 class, 0.2 class for high-precision sampling
Convenient and firm installation with bracket fixing and pressure plate fixing options
All cores undergo high-temperature heat treatment under nitrogen protection, ensuring excellent performance and stable precision
Light blue heat resistant housing (120℃) with flame retardant grade V0/V1, lead-free process and RoHS2.0 compliance
