Square Combined Residual Current Transformer

Product Overview

The circular combined residual current transformer is mainly used in the cable circuit environment.It has simple structure, small volume and flexible application. According to the specifications of the cable used in the main circuit, there are a variety of through hole diameters. The through hole diameter of this series of products ranges from 45mm to 100mm, and the main circuit current includes 63A to 2000a. This series of products can meet the technical requirements of grade 0.2, grade 0.5, grade 1 and other different precision; at the same time, it can also meet the strict requirements of the new national standard for balance characteristics, and the unbalanced current output value can be better than 30mA, 10mA,5mA,even 3mA, greatly reduces the false alarm caused by the interference of current and magnetic field in the main circuit, and provides 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 GB 14287.2-2014.
