Product Description
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. Major applications include ground fault relays, current measurements, power monitoring and over/under current sensing. This series of transformers provides the benefit of a high accuracy remote monitor for cost sensitive projects. Our General Purpose designs are made from the highest quality silicon steel cores available, and meet most of the common AC current measurement needs. A line of Ground Fault (-G) CTs for measuring low AC currents including electrical shields.
