Structural features

Silver pieces made by the melt of variable cross-section high-strength ceramic package in made by the melting tube; melting tube filled with chemically treated high-purity quartz sand as arc-quenching medium; melt welding and the use of two-terminal contact head strong electrical connection. Fuse type of well-off knife-shaped tube and square tube plate-shaped contact contacts two. Can fuse with indicator or striker, when the fuse melts, the indicator / impactor immediate action to show fuse is blown (indicator) and promote micro-switch (the impactor), issued a variety of signals or automatic switching circuit.
