摘要

The device has first and second housings (1,2), at least one electrical device in the first housing and an electrical conductor (3) leading to the electrical device. The first housing (1) is a fire protection housing that guarantees functional maintenance of the electrical device for at least one first period in the event of a fire. The second housing (2) has fire protection material (8) on its inner wall that foams in a fire situation and covers the first housing to guarantee longer function maintenance than for the first period.
