A fuse is called an electronic fuse in the sense of electrical engineering. A fuse is a protective device designed to protect against overload and short circuit. This means that the protective device independently switches off a circuit in case of a short circuit or overload. The electronic fuse is triggered when the current flow is too high and is thus interrupted at a certain current intensity. The fuse 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. This type of protection device is called an overcurrent protection device. This type of protection can be divided into three categories. A distinction is made between protection against overload and short circuit, protection against short circuit and protection against overload. In addition to protection against short-circuit currents, there are other types of fuses in the field of electrical engineering. For example, another common type is the melting fuse. This type of fuse interrupts the circuit to protect the fusible conductor from melting. The same principle works here. If the current exceeds a set value within a period of time, the circuit is interrupted by the fuse to protect the component.
