When using low-voltage fuses, note that
so as not to increase the contact resistance, causing the temperature rise and malfunction
fuse should be installed vertically to ensure that the socket and the knife holder in close contact,
he correct choice of melt. Fuse and line voltage is the same, the rated current of the melt is less than the rated current of the fuse;
single-phase line should be installed on the neutral line fuse; in the three-phase four-wire loop on the neutral line, the use of zero protection on the zero line is strictly prohibited fuses;
