PE Range Moulded Case Current Transformers

An extensive range of high quality current transformers offering comprehensive

measuring class accuracies. The PE range provides accurate measurement of high

primary currents, converting to a 5 Amp secondary current, proportional to the

primary current. To suit the requirements of most applications, the range offers a

wide selection of system current ratings, busbar sizes, case widths and apertures.
