  • overvoltage protection devices The mentioned basic elements of overvoltage protection devices and the corresponding overvoltage protection devices have been known for many years; they are used to protect electronic devices and electrical installations from overvoltages. Overvoltage protection devices can be intended for various applications, and a distinction is often made between overvoltage protection devices for protecting power supply networks and overvoltage protection devices for protecting signal lines or extra-low voltage lines. For the present invention, it does not depend on the type of voltage (s) to be transmitted by the overvoltage protection device.
  • the electrical voltage to be transmitted by the overvoltage protection device and / or the electrical current to be transmitted and / or the electrical power to be transmitted are fed into the overvoltage protection device via the first receptacle for receiving the first electrical conductor, i.e. from the unsecured side, and are fed out of the overvoltage protection device via the second receptacle for receiving the second electrical conductor, that is to say into the side protected against overvoltage.

  • Support rails are usually designed as metallic profile rails, often as so-called “top hat rails”. If the mounting rails are assigned an electrical potential, then it is usually the earth potential of the electrical system. This electrical potential of the mounting rail is then often used to implement the overvoltage protection as insulation strength protection between signal conductors and earth.
