Rectangular Open-close Type Current Transformer

Product Overview

The open-close 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 50A~6000A, 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.

Product Features

▪ Open and close structure,easy to install.
▪ This series of products have 6 specifications, and the primary currentrange is within 4000A.
▪ The secondary output is the standard signal of 5A-1A.

Scope of Application

Power monitoring, energy consumption management, intelligent power system,electromagnetic relay protection,microcomputer protection, motor protection, rural power grid transformation,substation transformation, environmental protection detection,etc.
