The CTK series split core current transformers are designed with split core silicon steel or nanocrystalline cores, wound with pure copper enameled wire, and the housing is crafted from high-toughness flame retardant PA66 material. Characterized by snap-on split structure for easy installation, high sensitivity and stable precision, they are ideal for power transformation and monitoring applications.
Primary current 5A-500A, secondary current 1mA-5A, inner hole size 10-50mm with diverse specifications
0.5-2 accuracy classes available, with phase error ≤120′ for 0.5 class products
All cores undergo high vacuum heat treatment, ensuring excellent performance, stable precision and high sensitivity
High-toughness flame retardant PA66 housing with good anti-aging performance and aesthetic appearance
Snap-on split structure enables quick and convenient installation without complex operation
