In electrical engineering terms, a fuse is referred to as an electronic fuse. A fuse is a protective device designed to protect against overloads and short circuits. This means that the protective device automatically switches off a circuit in the event of a short circuit or overload. The electronic fuse is triggered when the current flow is too high and is therefore interrupted at a certain current level. The fuse therefore protects against overcurrents. The electrical fuse only protects against overload and short circuit, never against electric shock to persons. Electronic fuses are always connected in series in the circuit so that the entire current must flow through them. This type of protective device is known as an overcurrent protective device. This type of hedging can be divided into three categories. A distinction is made between overload and short-circuit protection, short-circuit protection and overload protection. In addition to protection against short-circuit currents, there are other types of fuses in the field of electrical engineering. Another common type is the fuse. This type of fuse interrupts the circuit to protect the fusible link from melting. The same principle applies here. If the current exceeds a set value within a certain period of time, the circuit is interrupted by the fuse to protect the component.
