HV Current Limiting Fuse Type F
F type High voltage current-limiting fuses has two installation:bus-bar installation and insert installation.it is small in volume. reliable in connection and convenient in snstall and removal. The power striker parallels to fuse element made from pure silver . They are sealed ,in the fuse tube filled with chemically treated high-pu rity quartz sand. the fuse tube is made from heat resistant, high duty ceramic or epoxy glass. When fault circuit happens the fuse link melts, the high-resistant metal wire paralleling to fuse links melts immediatedly at the appearamce of the arc, and the striker jumps out to push the chained equipment contact, signaling the melting or automatically cutting the circuit ,The striker has spring type and powder to push the striker.F type fuse can reliably break the fault circuit which causes the fuse link to melt and which is up to the rated breaking current.it is not only featured with high breaking capacity of the current -limiting fuses, but also with protection of low ocerload of the un-current-limiting fuses. F type fuse had a protection of full scope breaking capacity.
Rated Voltage(KV): 12KV Rated Current(A): 6.3,10,16,20,25.31.5,40,50,63,80,100
Rated Voltage(KV): 24KV Rated Current(A): 6.3,10,16,20,25.31.5,40,45
Note:Under stipulated condition, min breaking currnet of fuses could be as high as 2.5~3 times than rated current.
