Disconnector with thermal melt-type fuse - has fuse holder designed to prevent manipulation reducing contact pressure

摘要

The disconnector has a fuse holder (2) inside its casing (1). The holder can move but is prevented from being removed. The holder has a contact piece (7) that forms a partition for the fuse chamber (13). The contact piece (7) can move in the direction of insertion. The holder is held in place by a guide slot (9) which has a stop (15) and a spring (8). Alternatively, the holder may have a ratchet-type piece and is held in its 'in' position when the operating lever (3) is in its 'on' position.
