Widely used internationally in revenue and switchboard applications by engineering, construction, and power companies, CIC Current Transformers are the result of over 40 years of manufacturing expertise, combined with technology transferred from Messwandler-Bau (MWB) of Germany.

The primary insulation material for CIC's current transformers is the Araldite® epoxy resin, known for its reliability. The outdoor models make use of cycloaliphatic epoxy resin, similarly to ensure high-quality insulation.

CIC's current transformers, including OEM/ODM products, are type-tested and routine-tested by CIC-owned, TAF-accredited Advanced Electricity Laboratory (TAF, or Taiwan Accreditation Foundation, is a member of ILAC and a signatory to the ILAC MRA).

  • Extended Range Current Transformer (ERCT)
    Extended Range Current Transformer (ERCT)

    Consider using an ERCT (Extended Range Current Transformer) instead of an ordinary current transformer because utility companies are employing metered level current transformers for revenue calculation. A regular current transformer may not be able to detect the current when the load is below 5% (off-peak period). In such cases, consumers may be using electrical services free of charge. An ERCT will solve this issue. CIC is proud to present this cutting-edge product to our global clients.
