Abstract: A circuit breaker system is disclosed in the present application. The circuit breaker system includes a housing to hold an electrical interrupter within an internal region separated from an external ambient region. The electrical interrupter includes at least a first pair of electrical contact elements that are movable between open and closed positions. A voltage limiter, such as a metal oxide varistor (MOV), is connected across the pair of electrical contact elements to receive and dissipate a transient voltage when the first pair of electrical contacts is moved from a closed position to an open position, thereby reducing undesired arcing and premature wear or erosion of certain electrical components.

Abstract: A surge arrester (100) and a method for manufacturing the surge arrester (100), the surge arrester (100) comprises a preassembled active part (110) extending in a longitudinal direction (Y), and a separately produced flexible housing (120) defining a bore (121) in the longitudinal direction (Y) and having an opening at an end surface (126) of the flexible housing (120), the flexible housing (120) is arranged surrounding the active part (110) via the bore (121) and in contact with the active part (110), the contact causes a deformation of the flexible housing (120) in a circumferential direction (C), and the deformation generates a pressure applied on the active part (110) along a radial direction (R).
