Fuse link

摘要

In the case of a fuse link which is used for temperature limiting and has a closed housing (1) in which a spring mechanism (2, 3, 4) interrupts an electrical contact as soon as a fuse body (6), which is used as a bearing for the spring mechanism, becomes liquid and relieves the load on the spring mechanism, the fuse body consists of an inorganic salt or a eutectic mixture of inorganic salts which are chemically stable up to the melting temperature and do not react with the metal parts of the fuse interior and do not suffer any phase change in the solid state. <IMAGE>
