Combined Current Transformer

Circular combined 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 45mm to 100mm, 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, even 3mA, which greatly reduces 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.

Rectangular combined 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 diameters. The through hole diameter of this series of product ranges from 100mm to 490mm, and the main circuit current includes 63A to 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.
