A housing for equipment in electrical systems, which is suitable for fastening to a wall or bottom surface, includes a substantially parallelepiped housing body. A bottom part is secured to the housing body and has an outer surface. A replaceable or interchangeable fastening adaptor is adapted to an intended type of wall or bottom fastening. Retaining elements, which are preferably of the same material, are formed on the outer surface of the bottom part for enabling the fastening adaptor to be slipped on.

Housing suitable for wall or bottom fastening

An apparatus for detachably fastening an equipment housing to a profile rail, preferably a top-hat rail mounted on a wall or bottom surface, includes guide strips. At least one clamp part slides on the guide strips and engages the profile rail in a clamping position like a tong. The at least one clamp part is retained in a clamping position by spring force operating in a given direction and is displaceable into an open position counter to the given direction for loosening. At least one locking part is displaceable relative to an equipment housing and is coupled to the at least one clamp part. The at least one locking part and the at least one clamp part occupy at least two positions defining a mutual spacing. The at least one locking part blocks the at least one clamp part in one of the positions for preventing the at least one clamp part from being displaced into the open position for loosening the equipment housing from the profile rail.
