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.
