The difference between the fuse and the air switch
The air switch is normally used for the opening and closing of the main power supply, and the quick fuse is used for the protection of a single electrical equipment
Empty can be reset, fast melt can only be replaced
The air switch disconnects all of the power supply from the faulty circuit
fast fuse in the fault can only disconnect the three-phase power phase or two phases, and electrical equipment is charged
fast fuse is mainly when there is short-circuit over-current, over-voltage can be timely blow to protect the load and line normal to prevent accidents, failure to expand.
