Abstract
The invention relates to a fuse system for a switchgear assembly, especially for a medium voltage switchgear assembly. The fuse system comprises a plurality of fuses which correspond to the number of phases, every fuse having a tripping bar that projects from the face of the fuse under the effect of the force of a spring when the fuse comes into action. A sealing body, with a spring arrangement interposed, pushes a sealing head into the interior of a receptacle receiving the fuse. A two-armed lever is received on the sealing head, one arm covering a tripping mechanism which actuates a power switch.
