The short circuit basically consists of a connection without resistance, existing between conductors under voltage or in some cases can be considered as an intentional or accidental connection between two points of an electrical system or equipment, or of an element, through an impedance unsatisfactory. Fuses refer to components used for the purpose of performing their main function, which is to limit the current of a circuit, providing its interruption in case of short circuits or long overloads.
Its operation is based directly on the fusion of a component by the Joule effect, caused by the sudden rise of current in a specific circuit. The fuse component has physical properties such that its melting point is less than the melting point of copper, and it is the most sought after material used in conductors of different applications. Thus, by means of a transient resistance, the current may have a value greater than the operating current. Thus, the equipment GF1524BG and part of the installation may undergo a thermal stress, ie, a short-lived, or electrodynamic, suppressor current, which is an excessively high rated impulse current.
