ABSTRACT:
The head member of the fuse holder can be removed from a socket member along an insertion axis when pressure is brought to act on spring detents or latches. The non-similarity of the spring detents ensures that the head member only can be inserted into the socket member in one predetermined orientation or position. The fuse holder which, for instance, is a two-pole fuse holder, in addition to an entirely conventional fuse and the associated holder including connection tabs in the socket member, comprises a further fuse which is associated with a line voltage preselector. For this purpose a selector insert is removably seated and locked into position in the head member along the insertion axis. A connecting conductor finger of the selector insert, depending on its rotary position within the head member, contacts a preselectable one of four lateral or side connection tabs. Therefore, the voltage cannot be unintentionally misadjusted when a fuse is exchanged.
