Overview
A straight-through current transformer is mainly used in cable circuits and features a simple structure, compact design, and flexible application. There are several straight-through bore diameters to suit different cable specifications in the primary circuit.
This series of products can meet accuracy levels 0.2, 0.5 and 0.3, and can also meet the stringent requirements on balance
characteristics as defined in new national standards. The unbalanced current output value can also be better than 30 mA, 10 mA,
5 mA, or even 3 mA, greatly reducing false alarms caused by magnetic field interference in the primary circuit, providing
guaranteed protection for the reliable operation of the equipment. Advanced production process guarantees its accuracy level,
reliability and other technical requirements. This series of products meet the requirements defined in GB14287.2-2014.
