Plug-presence auxiliary contact

 

This is an accessory developed for SCAME's OPTIMA Series flush-mounting sockets whose function is to indicate the "plug-presence" state or provide consents to plug in or unplug the device through a clean auxiliary contact, available in the NO and NC version.

Its applications are endless, so only a few examples are provided here below:

  • sending electrical signals for the use of management software of the systems the indication of “plug-presence” state.
  • this application is especially useful in case you need to monitor loads a well as to have constant service continuity (for example, refrigerators, refrigerated containers, air extractors, etc.), or in the case of monitoring the use of services in public areas, such as camping grounds, piers, or during events in public areas.
  • creating electrical interlocks both directly through the same contact for small mono-phase powers (10A 230V), since it is equipped with power contact or in case of higher or three-phase powers through the command of a contactor.
  • this application is especially useful to energize the socket only when the plug is totally plugged in , for both safety reasons, since there is no voltage on the socket contacts when the plug is unplugged, and to ensure the complete insertion of the plug, thus eliminating the risk of improper connections.
  • especially useful to ensure safety in public areas such as camping grounds, outdoor markets, tradeshows or events, playing grounds, tourist harbours, and to make it necessary for the plug to be completely plugged in order to energize the socket.
