Rectangular Current Transformer

Square through type residual current transformer is mainly used in cable circuit environment. It has simple structure, small volume and flexible application. According to specifications of the cable used in the main circuit, there are various through hole diameter. The through hole diameter of this series of products ranges from 100mm to 450mm, and the main circuit current includes 63A ~ 2000A. This series of products can meet the technical requirements of 0.2 level, 0.5 level and 1 level and other difference precision. At the same time, it can also meet the strict requirements of the new national standard for the balance characteristics. The unbalanced current output value can also be better than 30mA, 10mA, 5mA,  or even 3mA, greatly reducing the false alarm caused by the magnetic field interference of the main circuit current, providing sufficient guarantee for the reliability of the equipment. Excellent and advanced production process. This series of products meet the requirements of GB-14287.2-2005 and GB14287.2-2014.  

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 ~4000A, 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.
