ICT-CTK Open-Close Type Circular Residual Current Transformer

Name: ICT-CTK Open-Close Type Circular Residual Current Transformer
Availability: InStock

Circular switching residual current transformer is mainly used in cable circuit environment. It has simple structure, small volume and flexible application. According to the specifications of cable used in the main circuit,it has a variety of through hole diameter. The through hole diameter of this series of product is from 30mm to 200mm, and the main circuit current includes 63A ~ 2000A. The series of products can meet the technical requirements of different precision such as 0.2, 0.5 and 1. 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 interference of the current and magnetic field of 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 GB14287.2-2014.
