LO-CTK/N-20 split core residual current transformer

 

Introduction

 

The residual Current transformer is mainly used in cable circuit environment. Its simple structure, small size and flexible application make it very suitable for the cable specifications used in the main circuit. The diameter of this series of through holes ranges from 30mm to 200mm, and the main circuit current includes 63A to 2000A. The residual current transformer can meet the technical requirements of different precisions such as 0.2, 0.5, and 1, and can also meet the strict requirements of the new national standard. Balanced characteristic standard. The unbalanced current output value can also be better than 30mA, 10mA and 5mA. Even 3mA greatly reduces the false alarm caused by the interference of the main circuit current and magnetic field, and provides a sufficient guarantee for the reliability of the equipment. Excellent and advanced production process. In order to ensure technical requirements such as accuracy level and reliability, this series of products meet the requirements of GB-14287.2-2005 and GB 14287.2-20140.
