Active/Passive RCD Guide

13A RCD ACCESSORIES

In the latching or Passive units the RCD will remain closed, once set, and will only trip when a hazardous earth fault occurs. If the unit loses supply - perhaps in a power cut - it will stay latched, making it particularly useful in commercial applications, such as controlling refrigeration units.

Non latching or Active units also trip when the power supply is lost, so they are useful for domestic applications - like controlling garden and power tools - where a sudden restoration of power might pose safety problems.

The surface of the sockets will be warm even when the socket is not in use. The surface can safely attain a temperature rise of 52°C when the RCD is on load. Without a load it can be expected that the surface would reach 38°C.

The internal parts are tested to 66°C to comply with the standard

The above information generally applies to the Connection Unit, which is latching type.
