CR8449-2000-F

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 (-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) are for measuring low AC currents including electrical shields. Nanocrystalline (-A) is the most versatile providing accuracy, high saturation point and a linear response in high frequency applications. The High Frequency (-F) products are designed for high frequency applications such as high frequency power supplies and motor drives. GENERAL PURPOSE CURRENT TRANSFORMERS Ir Vmax RMS Te (typ.)
