a. High speed High Breaking Capacity fuse 2500v 500a
The speed at which a fuse blows depends on how much current flows through it and the material of which the fuse is made.
Fuse have different characteristics of operating tme compared to current, characterized as fast-blow, slow-below, or time-delay, according to time required to respond to an overcurrent condition.
Semiconductor devices may use a fast or ultrafast fuse as semiconductor devices heat rapidly when excess current flows.
The fastest blowing fuses are designed for the most sensitive electrical equipment, where even a short exposure to an overload current could be very damaging.
c.The I2t value:
The amount of energy spent by the fuse element to clear te electrical fault. This term is normally used in short circuit conditions and the values are used to perform co-ordination studies in electrical networks. The energy is mainly dependent on current and time for fuses as well as the available fault level and system voltage.
The breaking capacity is the maximum current that can safely be interrupted by the fuse. Generally, this should be higher than the prospective short circuit current. Some fuses are designated High Rupture Capacity and are usually filled with sand or a similar material.
