Selection Of Types Of RCD

RCD's exist in various different forms and react differently depending on the presence of DC components or different frequencies.

The following RCD's are available with the respective symbols and the designer or installer is required to select the appropriate device for the specific application.

RCD Types

  • Type AC - General purpose use, RCD can detect & respond to AC sinusoidal wave only.
  • Type A - Equipment incorporating electronic components RCD can detect & respond as for type AC, PLUS pulsating DC components.
  • Type F - Equipment with frequency controlled speed drives RCD can detect & respons as for type A, PLUS high frequency residual current.
  • Type B - Electric vehicle chargers, PV supplies.

    RCD can detect & respond for type F, PLUS smooth DC residual current.
