CTBHIII series products are made of flame-retardant polycarbonate engineering plastics, with excellent high temperature resistance, high strength and strong impact resistance. They can be widely used in copper busbar power distribution environments.
This series of products is made of large-section high-magnetic silicon steel materials and high-quality enameled round copper wires. They have strong anti-saturation ability, high accuracy, large load capacity, and low self-heating of the transformer.
Because the protective current transformer is large in size, heavy in weight, and has strong overload capacity, when it is used, it needs to be firmly fixed on the busbar to prevent it from loosening due to vibration during transportation. It is also necessary to reliably connect the secondary side of the transformer and the input end of the protection device, otherwise the high voltage generated by the primary current will pose a greater threat to people and equipment than other types of products.

All products in the CTBHIII series use terminal output.
