Definitions

  • the invention is based on a contact arrangement for a fault-protected socket according to the introductory part of claim 1.
  • Fault-protected sockets prevent electrical accidents and fires in electrical systems. They continuously monitor the connected consumers and cut off the power supply before a fault current flowing to earth can be dangerous for people, animals or things.
  • the contact arrangement provided for power interruption in the socket should be as simple and space-saving as possible. In addition, it is desirable that the contact assembly be easy to assemble and maintain.
  • a leakage current-protected socket specified in this patent document contains two fixed contact pieces 47, 53, which each cooperate with one of two movable contact pieces 49, 51, which in turn are each fastened to a spring-loaded movable contact arm 41 by means of a contact plate 115, 127.

Plug-in connections designed as sockets for power consumers and actuators for the contact arrangement of the residual current circuit breaker and for a test circuit are led from the inside of the housing to the front of the socket.
  • the housing has a material recess on the back of the socket for receiving screw terminals for connection to the conductors of a power supply network.
  • this socket To achieve a compact design, the individual components of this socket are screwed onto a mounting body made of insulating material and / or screwed together.
  • the manufacture and maintenance of the contact arrangement of such a socket are quite complex. Comparatively many assembly steps are required for the manufacture of the contact arrangement and its installation in the socket.
  • the connection of the contact arrangement to the power supply network takes quite a lot of time when installing the socket.
  • the invention has for its object to provide a contact arrangement for a fault-protected socket, which is simple, easily installed in the socket and very quickly connected to the power supply during installation of the socket or during maintenance of the Socket can be disconnected very quickly.
  • the contact arrangement according to the invention is characterized in particular by the fact that its individual components are modular units which are plugged together to form the contact arrangement on components of the socket which are present anyway.

  • the conductor sections 121 and 122 are wound around a ferromagnetic core of a summation current transformer 4 of the residual current circuit breaker and act as its primary winding.
