MC-Sockets type BL...N are distinguished by their simple handling.
To make contact, the plugs S...N or SP...N are simply pushed-in and to disconnect, are pulled-out.
The MC-Sockets are suitable to screw directly into busbars (tube or flat profile), into contact blocks, conductor rails, housing, etc.
The sockets are slotted at one end suitable for the appropriate mounting tool.
The BL-sockets with external thread must be screwed against a fixed stop, or screwed into the busbar with 2 nuts and 2 washers.
For extreme loads and mounting conditions and where a stop is not possible,
a socket with external Multilam instead of a thread is available (see BL...A).
Before assembly the threads must be covered with a thin lubricating film
