High Ratio Wire Lead Transformers  
CR Magnetics CR8400 Series of Wire Lead Current Transformers are  
available in a wide range of sizes and materials to meet any AC current  
sensing needs. Our General Purpose designs are made from the  
highest quality silicon steel cores available, and meet most of the common AC  
current measurement needs. Our Revenue Grade CTs (-N) are made  
from a nickel alloy core which provides the most linear response over  
temperature and current level. A line of Ground Fault (-G) CTs for  
measuring low AC currents including electrical shields. The High  
Frequency (-F) products are designed for high frequency applications such  
as high frequency power supplies and motor drives.
