What is the main purpose of the electric fuse of the stacker?

The main purpose of the electric fuse in a stacker is to provide short circuit protection. When a short circuit occurs, it creates a low-resistance path that can draw excessive current, potentially damaging the electrical components or causing a fire hazard. The fuse acts as a safety device that will break the circuit by melting its element, effectively stopping the flow of electricity and preventing damage to the system.

While overload protection is an important aspect of electrical safety, fuses are specifically designed to react to fault conditions like short circuits, which are characterized by instantaneous high currents. Voltage regulation and current interruption, while they may involve aspects of electrical systems, are not the primary functions of a fuse. Therefore, the electric fuse is crucial for ensuring that the stacker operates safely and that the electrical components are protected against the risks associated with short circuits.
