1.Prevent overload burnout
When a circuit shorts out or the load is too heavy, the current surges sharply. The fuse will melt prematurely to prevent the wires from overheating and catching fire, or damaging expensive components such as motors and controllers.
2. Isolate the faulty point
If there is a problem with the circuit of a certain electrical appliance, only the fuse of that circuit should be blown, without affecting the normal operation of the other parts of the forklift. This also makes it easier to identify the fault.
