Model HRW7-10 / 200A high drop-out fuse and pull the load drop fuse is outdoor high-voltage protection of electrical, it fitted in the high pressure side of the distribution transformer or distribution lines branch trunk road, as transmission lines, electric power transformer overload and short circuit protection . and division and rated load current with fuses according to the protective effect, the large breaking current should not be less than the maximum short-circuit protection of electrical current; the minimum melting current should be no greater than the minimum short-circuit current protection circuit.
Fuse should be stored in a dry place suitable. When replacing the fuse action had, should be replaced after 10 minutes in the action. If the action after the discovery of the inner tube fuse escape smoke or noise phenomenon and should not replace the fuse, you need special fuse and power isolation after allow replacement.
