The invention relates to a disconnection and switch-over device for overvoltage protection, particularly for DC systems, comprising at least one arresting element, and a thermal cut-off point incorporated into the electrical interconnect path of the arresting element, the thermal cut-off point comprising a movable mechanically prestressed conductor element that moves from a first position to a second position in the event of a cut-off, and when the second position is reached, an electrical switch-over to a safety device is generated, and the thermal cut-off point is formed by the movable conductor element and a stationary contact element, the movable conductor element being attached to the stationary contact element by a thermally releasable means. According to the invention, a completely electrical cut-off of the arresting element regarding the interconnect path only occurs when the movable conductor element has gone beyond the second position and has reached a third position, the safety device being arranged in series with the arresting element and the movable conductor element being designed as a wiper or sliding contact in relation to the second position, the second position being created by a bypass end point. 11124122.

The invention relates to an overvoltage protection arrangement having: a plurality of planar varistors , which are arranged on a first side of a supporting plate ; at least one gas arrester ; and at least one thermal disconnection device, which is in close thermal contact with at least one of the varistors. The aforementioned components are surrounded by an outer housing , and electrical connection means for soldering to a printed circuit board are also provided on the second side of the supporting plate. The varistors have a parallel stack arrangement, which is delimited on each of two opposing sides by an insulating partition wall which can be attached to the supporting plate. Each partition wall has at least one opening for a varistor terminal (), each varistor terminal being connected to a thermal disconnection device, which in turn comprises a spring-loaded disconnecting lever (), the respective disconnecting lever being connected at its first end to the respective varistor terminal by a soldered connection () and wherein its second end merges into one of the electrical terminals and penetrates through the supporting plate . The thermal disconnection device also has an insulating slide , whose free end acts on the disconnecting lever (), wherein the slide runs in recesses in the respective partition wall , and a change in the position of the slide can be seen by means of a viewing opening in the outer housing 12212271017. Overvoltage protection arrangement having a plurality of planar varistors (; ;) arranged on a first side of an n-cornered supporting plate () , at least one gas arrester () and at least one thermal fuse or thermal disconnection device , which is in close thermal contact with at least one of the varistors , the aforementioned components being surrounded by an outer housing () and furthermore means for electrical connection being provided on the second side of the supporting plate () for soldering on a printed circuit board ,characterized in ...
