WebIn 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. Latched RCD Accessories WebThe passive state exists when the metal is covered by a thin oxide layer and is protected from the contact of contaminants. This is in contrast to the active state, where the base metal is exposed. The passive layer is the thin outer ilm (measured in Angstroms) that exists on the surface of the metal.
