FUSE ELEMENT FOR ELECTRICAL FUSES

摘要

The invention relates to a fuse element for electrical fuses which comprises laminated copper flat cross bars (1) alternating with silver flat cross bars (2), so that the holes (4) and the isthmuses (5) be cut in the silver flat bars (2). Such a structure of the fuse elements cuts the consumption of pure silver used in manufacturing fast-acting fuses by 65...85%, depending on the rated voltage of the fuse.
