Abstract
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.
