Introduction

The center through hole current transformer is mainly used in the cable circuit environment.Its structure is simple,small in size,flexible in application,and well fit the cable specifications used in the main circuit.The diameter of the through-hole this series is from 30mm~200mm,the main circuit current contains 0A~2000A.This series of products can meet the technical requirements of different precisions such as 0.2,0.5,and1. At the same time,it can meet the stringent requirements of the new national standard for balance characteristics.The unbalanced current output value can also be better than 30mA,10mA,5mA.Even 3mA greatly reduces the false alarm caused by the main circuit current magnetic field interference,which provides sufficient for the reliable of the equipment.Excellent and advanced production process.To ensure the accuracy level reliability and other technical requirements,this series of products meet the requirements of GB-14287.2-2005 and GB14287.2-20140.
