  • the first connection element is connected via a flexible conductor to a rigid separation element whose end remote from the flexible conductor is connected via a solder joint to a connection lug provided on the varistor.
  • the other connection element is connected via a flexible conductor fixed to the varistor or a terminal lug on the varistor.
  • the separating element is acted upon by a spring system with a force which results in the separating element being linearly moved away from the connecting lug during the separation of the soldering connection, with the result that the varistor is electrically cut off in the event of thermal overloading.
  • an overvoltage protection element in which the monitoring of the state of a varistor according to the principle of a temperature switch, so that when overheating of the varistor a provided between the varistor and a separator solder joint is separated, resulting in an electrical separation of the varistor.
  • a plastic element is pushed by the restoring force of a spring from a first position to a second position in which the formed as a resilient metal tongue separating element is thermally and electrically separated from the varistor by the plastic element, so that a possibly between the metal tongue and the contact point of the varistor arcing arc is deleted. Since the plastic element has two color markings arranged next to one another, it also simultaneously functions as an optical status indicator, so that the state of the overvoltage protection element can be read directly on site.
  • the DE 695 03 743 T2 discloses an overvoltage protection element with two varistors, which has two separating means, which can individually separate the varistors at their end of life.
  • the separating means each have a resilient separating tongue, wherein the first end of the separating tongue firmly connected to the first terminal and the second end of the separating tongue is attached in the normal state of the overvoltage protection element via a solder joint to a connecting tongue on the varistor. If there is an inadmissible heating of the varistor, this leads to a melting of the solder joint.
  • the separation tongue Since the separation tongue is deflected in the soldered state (normal state of the overvoltage protection element) from its rest position and thus biased, the free end of the separation tongue springs when softening the solder joint of the connecting tongue of the varistor, whereby the varistor is electrically disconnected.
  • the cross section of the separation tongue may not be too large, so that it has a sufficient spring property.
  • this also leads to a limitation of the maximum permissible pulse current.

  • An inadmissible heating of the varistor also leads here to a heating of the solder joint, so that the slider is pulled due to the force acting on it a spring from the junction between the first terminal and the terminal lug, resulting in an electrical separation of the varistor.
  • the DE 10 2007 042 991 A1 discloses an overvoltage protection element comprising a housing, at least one varistor disposed in the housing, a pair of metallic stirrups as the electrically conductive connecting element, a spring, and a spring loaded slide as part of a mechanical severing device.
  • the mutually parallel ends of the two current-dividing metallic bracket take in their midst a contact lug of the varistor, wherein the closed position is secured by a solder.
  • the bracket enclose a space in which the spring-loaded slider is arranged.

  • thermal separation devices which are based on the melting of a solder joint, have to fulfill several tasks.
  • a secure and good electrical connection between the first connection element and the overvoltage limiting component must be ensured.
  • the separation point When a certain limit temperature is exceeded, the separation point must be a safe separation of the overvoltage limiting component and a permanent insulation resistance and tracking resistance guarantee.
  • overvoltage protection element moreover have the smallest possible dimensions so that the overvoltage protection devices do not exceed the dimensions specified for DIN rail devices, this leads to the known overvoltage protection devices being able to be used only in the lower and middle power classes, ie for pulse currents ⁇ 65 kA.
  • the present invention is therefore based on the object to provide an initially described overvoltage protection element, in which the aforementioned disadvantages are avoided. It should be ensured both a safe and good electrical connection in the normal state and a safe separation of a defective overvoltage limiting device. In addition, the highest possible insulation and tracking resistance should be achieved even with the smallest possible size of the overvoltage protection element, so that the overvoltage protection element can derive the highest possible pulse currents.
  • the electrically conductive connecting element which is arranged in the normal state of the overvoltage protection element between the second terminal contact and the second pole of the overvoltage limiting component and electrically connected to both, is connected to an insulating separating element that with a disconnected thermal connection between the second terminal contact and is arranged on the second pole of the overvoltage limiting component, a possibly resulting when opening the separation point arc is reliably deleted by the retracting into the separation point insulating separator.

  • the release carriage thus serves to move the electrically conductive connection element out of the intermediate space between the second connection contact or the rigid metal connection element connected to the second connection contact and the second pole or the connection lug connected to the second pole. Since the conductive connecting element is firmly connected to the insulating separating element, the separating element is simultaneously moved into the intermediate space.
  • At least one driving hook is arranged on the release carriage, which receives a portion of the insulating separating element.
  • the insulating separating element is thus, preferably at its lower edge, received by the driving hook, so that the insulating separating element - and thus the conductive connecting element - is moved during the movement of the trigger slide from the first position to the second position upwards, so that the Pushed connecting element out of the intermediate space and the insulating separating element is pushed into the intermediate space.
  • the connecting element is thus the only current-carrying element which is movably arranged.
  • the metallic connection element like the connection contact, is rigid, so that both elements can be designed to be correspondingly robust and with a correspondingly large cross section, in order to be able to transmit large pulse currents safely.
