Abstract: An overvoltage protection spark gap assembly includes a first overvoltage protection spark gap (1) which has a first main terminal (1a) and a second main terminal (1b); and a second overvoltage protection spark gap (1?) which has a third main terminal (1a?) and a fourth main terminal (1b?). The second main terminal (1b) and the third main terminal (1a?) are electrically connected together. A first electrically conductive probe device (K2) is introduced into a wear part (38) of the first overvoltage protection spark gap (1) such that, in the event of a specific degree of wear, the first electrically conductive probe device (K2) comes electrically into contact with an arc (41) in the first overvoltage protection spark gap (1). The second overvoltage protection spark gap (1?) has a second electrically conductive probe device (33) which comes electrically into contact with an arc in the second overvoltage protection spark gap (1?).

Abstract: The present invention provides an overvoltage protection spark gap assembly and a method for operating an overvoltage protection spark gap assembly. The overvoltage protection spark gap assembly comprises a first overvoltage protection spark gap (1) which has a first main terminal (1a) and a second main terminal (1b); a second overvoltage protection spark gap (1?) which has a third main terminal (1a?) and a fourth main terminal (1b?). The first main terminal (1a) can be connected to a first voltage line (S1) of a supply network via a first terminal contact (A1) and the fourth main terminal (1b?) can be connected to a second voltage line (S2) of the supply network via a second terminal contact (A2). The second main terminal (1b) and the third main terminal (1a?) are electrically connected to one another.

Abstract: The invention relates to a defect indicator for an electronic device, in particular a surge arrester, comprising at least two thermal overcurrent protection devices which respond to different fault or overload states and each have a mechanical actuating device for triggering the fault signalling, wherein the mechanical actuating device is in the form of a bolt or pin which acts on a fault signalling element. According to the invention, the at least two overcurrent protection devices are arranged relative to one another in such a manner that the direction vectors of the bolts or pins intersect in an imaginary extension of the movement path thereof, wherein the particular bolt or pin acts on a respectively provided surface side of a displaceable armature and the armature occupies a variable position in the movement path.
