Another HUNTINGTON ELECTRIC Company

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 CTs for measuring

low AC currents include electrical shields. The High Frequency (-F) prod-

ucts are designed for high frequency applications such as high

frequency power supplies and motor drives.
