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.
