5.Installation conditions
Normal working conditions
The fuses are installed separately in unventilated natural air, in addition to connecting wires, no other heat generating parts or heat dissipating parts within 1m.
The fuse connection terminals should ensure stable and reliable electrical contact; contact resistance should not significantly affect fuse operation.
The fuse can be installed vertically, horizontally or obliquely. If relying on spring pressure to ensure electrical connection fuse, when installing, a suitable location should be selected to avoid the adverse effects of gravity and vibration on the electrical connection.
