The enclosure is made of high-strength PC material with totally-enclosed structure. It is mainly used where the three-phase bus bar is arranged vertically and it is installed mainly by fixing bus bar.

The capacity of current transformer is increased and its precision is greatly improved, so that it can meet the higher requirements for the high impedance load and electric energy measurement.

Internal iron core adopts high-quality silicon steel sheet;

In conformance with GB0840.2-2014;

Pass the National Metrology Accreditation;

Secondary current is divided into 5A and 1A.
