Abstract
The fuse comprises an elongated support formed at least partially from ferrite, magnetized in the direction of its thickness and on which is disposed, between two terminals, a metal wire (9) capable of being destroyed by melting. The fuse comprises for example two ferrite strips (5 and 6) assembled together and spaced apart by means of two insulating-material bars (7 and 8), a silver wire (9) being disposed between the two strips. When the wire melts, the molten metal and the electric arc are driven laterally in accordance with the LAPLACE law.
Claims8
A fuse comprising a conducting wire (9) capable of being destroyed by melting in the case of an excess current;
- at least one elongated support means formed at least partially of ferrite (1) and having a top surface, a bottom surface and a thickness between said top and bottom surfaces, magnetized in the direction of its thickness and on which said conducting wire is disposed between two terminals (3, 4) spaced apart along said support means, said wire being supported along its entire length on one of said surfaces of said support means.
