About the Product

Intended for 15 kV (max.) power systems, the EO-10SC Series current transformers for indoor application are available in single-core and two-core types. With a rated primary current of 500~3000A (single-ratio or multi-ratio), these current transformers are insulated with Araldite® epoxy resin and can be used with measuring or monitoring instruments, or for protective purposes. The window-type design facilitates installation and wiring with a busbar or a suitably insulated primary conductor, decreasing the occurrence rate of contact point failure. Characterized by excellent physical and electrical properties, the EO-10SC Series current transformers have consistently met with a high level of customer satisfaction.

    Overvoltage Protector for Current-Transformer Protection
    CCTP-03

    When a power system is in operation, it is imperative that the secondary of the current transformer(s) should not have an open circuit. When an open circuit occurs, an extremely high transient voltage will be induced, which can in turn damage the current transformers and the instruments at the secondary, or even posing a threat to personal safety. This CT secondary overvoltage protector offers protection from such accidental damage caused by secondary transient voltage.
