The Single Pole Low Voltage Current Transformers are intended to supply measuring instruments and protective circuits of electrical power devices. Their maximum voltage is 500 V and frequency 50 Hz (or 60 Hz after a request).
They are manufactured for 5 A secondary current. The range of the primary current depends on the type of the Transformer and is between 200 – 1.500 A.
They operate in short – circuit conditions transforming the primary circuit current to the secondary circuit current. The windings of the Transformers are enclosed in the housing made of slow – burning material.
