A surge arrester is provided that comprises an elongate housing, an active member, and an enclosure. The elongate housing has an interior comprising an interior surface that extends along a longitudinal axis between a first end and a second end of said housing. The active member is arranged at least partially within the interior. The enclosure is fixed to or integrally with the housing and closes the interior at the first end. The enclosure comprises a predetermined breaking line. In the event of a fault condition, e.g., a short circuit condition, the pressure within the housing increases and the predetermined breaking line allows for a defined breaking of the enclosure.

A securing and centring device for securing fastening elements of a vibration damping device and for centring said vibration damping device on a component, such as a crankshaft. The securing and centring device may includes a securing mechanism that can be inserted into an opening of the vibration damping device and is configured to secure a fastening element inserted into the opening against falling out, a centering mechanism insertable into a further opening of the vibration damping device and into an assembly opening of said component for positioning and/or centering the vibration damping device and said component relative to each other, and a connecting member connecting the securing mechanism and the centering mechanism. A vibration damping device may include such a securing and centering device.
