Abstract (en)
[origin: DE4445061A1] The invention concerns metal-clad switchgear (1) comprising a gas-filled container (3) with a three-position disconnector (4) and a vacuum switching device (6). H.v.h.b.c. fuses are located outside the container (3) in air. The vacuum switching device (6) takes the form of a loss-of-vacuum protector with an electromagnetic mechanism (8) which is likewise housed in the container (3). The switchgear described is suitable in particular for controlling motors which have a constant sense of rotation or which commutate.
