Current and Voltage transformers are suitable for use with measuring instruments or plant protection devices. The standard operating voltage is 0.72kV and the frequency between 50 and 60Hz.

The CTs primary standard currents are between 1A and 8000A, the secondary currents are 1A or 5A.

Current transformers are designed for indoor installations and they are manufactured as thermal class E, on demand they can be supplied in higher thermal classes.
