    EWF-20DA Series

    This no-cut core - also referred to as ring core - has an iron core designed to give protection in a small magnetic resistor. The characteristics of this current transformer won't alter during operation. This model has a high accuracy rating and won't vibrate during use. This model designed with various terminals to meet customer requirements. When it is operating, secondary connection is not allowed to open circuit; otherwise it will occur inductance voltage damage. Therefore, while changing the connection of secondary side, must make sure to close the circuit before changing.

  • 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.
