Import Cp Series Current Transformer — Buy in Bulk from Supplier in China

The CP Series Current Transformer from Yueqing Heyi Electrical Co., Ltd. is a compact, high-accuracy instrument designed for measuring alternating current in industrial and energy monitoring systems. It features a nominal current ratio of 100:5 A and a burden rating of 2.5 VA, with an accuracy class of 0.5 for measurement applications and 5P10 for protection circuits. The core is constructed from high-permeability silicon steel, and the winding is insulated with class F epoxy resin, ensuring thermal stability under continuous load.

This transformer operates within a temperature range of -25°C to +70°C and meets IEC 60044-1 and GB 1208 standards for accuracy and insulation. Typical dimensions are 85 mm in length, 55 mm in width, and 45 mm in height, allowing installation in tight switchgear compartments. Unlike bulkier models, its toroidal design reduces magnetic leakage and electromagnetic interference, making it suitable for environments with sensitive control electronics. The secondary terminal is shielded and terminated with screw-type connectors for secure field wiring.

It is commonly used in energy meters, protective relays, and industrial automation panels where precise current feedback is critical. Buyers include electrical contractors, panel builders, and renewable energy system integrators across Southeast Asia and Eastern Europe. Trade terms include FOB Ningbo or Shanghai, with packaging in anti-static foam-lined cardboard boxes. Minimum order quantity is not specified in the listing and should be confirmed directly with the supplier.
