Product Overview

The clamp type current transformer is mainly used for cables and copper bars. It has simple structure, reasonable design and flexible application.According to the specifications of the copper bars used in the main circuit, there are many kinds of through holes corresponding to each other. The primary current of the main circuit includes OA~ 1000A, and the rated secondary output current is 1A~ 5A (0~1V).This series of products can meet the technical requirements of grade 0.2, grade 0.5, grade 1 and other different precision. GB/T20840.1.2.

Product Features

▪ Open and close structure,easy to install.
▪ This series of products have 5 specifications, and the primary current range is within 1000A.
▪ The secondary output is the standard signal of 5A-1A.
