    摘要： A disconnector and related surge arrester include first and second connection terminals connecting to active electrical leads, between which a protection element is inserted, having electrodes electrically connected to the connection terminals, a disconnector between the first terminal and an electrode of the protection element including a metal plate having a base end electrically connected to the first terminal and a distal end maintained electrically connected to the electrode, the plate being able to sublimate in the presence of short-circuit currents above a preset threshold, an intercepting slider, mounted longitudinally slidable along a longitudinal direction which lies between the base end of the lamina and the electrode of the protection element to intersect development of an electric arc, a sliding guide for the intercepting slider, the slider being biased in the longitudinal direction, through a preloaded elastic unit, towards an intercepting position abutting a portion of the plate.

    摘要： A surge arrester is disclosed comprising a first and a second electric terminal (1, 2) for connecting to the active leads of an electric plant, between which a protection element (3) is inserted provided with a pair of electrodes (4) electrically wired to said electric terminals, between said first electric terminal (1) and an electrode (4) of the protection element (3) a disconnector being provided comprising a conductive, resilient, flexible lamina (5) having a base end (5a) electrically wired to said first electric terminal (1) and a distal end (5d) maintained electrically connected to said electrode (4), in a state of elastic preload, by a welding with low-melt material. Lamina (5) is mounted elastically biased according to a direction so as to push said distal end (5d) away from said electrode (4) and it is made with a thickness below 0.5 mm and of a conductive material with a conductivity much lower than that of copper (IACS
