Intro：Circular open close type residual current transformers are mainly used in cable circuit environments. They have simple structure, compact size, and flexible application. According to the specifications of the cables used in the main circuit, there are various perforation apertures corresponding. The diameter of the perforation hole in this series of products ranges from 25mm to 200mm, and the main circuit current includes 63A to 2000A. This series of products can meet the technical requirements of different accuracy levels such as 0.2, 0.5, and 1; At the same time, it can also 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, or even 3mA, greatly reducing false alarms caused by current magnetic field interference in the main circuit, providing sufficient assurance for the reliability of the equipment. Excellent production process. This series of products meets the requir

Intro：Rectangular open and close residual current transformers are mainly used in cable circuit environments. They have a simple structure, small size, and flexible application. According to the specifications of the cables used in the main circuit, there are various through-hole apertures corresponding. This series of products have through-hole apertures ranging from 110mm to 300mm, and the main circuit current contains 63A to 2000A. This series of products can meet the technical requirements of different accuracy levels such as 0.2, 0.5, and 1; At the same time, it can also meet the stringent requirements of the new national standard for balance characteristics.
