The fuse is used in the medium- and high-voltage sector and has two
spaced-apart power supply connections (2, 3) and an active part (1). The
active part comprises a fusible, current-carrying fuse element and an
arc-extinguishing medium. The fuse element is connected in an electrically
conducting manner to the two power supply connections and is arranged on
an electrically insulating substrate. It is of a modular construction and
has at least two modules (9) connected in series. The arc-extinguishing
medium covers the exposed surfaces of the fuse element. The active part is
formed in the manner of a sandwich and has two stable moldings (4, 5) and
a predominantly planar intermediate layer (6) arranged between the
moldings (4, 5). The intermediate layer (6) contains at least the two
series-connected modules, whereas a first molding (4) of the two moldings
is formed at least by part of the electrically insulating substrate and
the second molding (5) is formed at least by part of the arc-extinguishing
medium.
The fuse is distinguished by a simple construction and by favorable
triggering characteristics.
