Note:
Current-limiting medium voltage fuses are
classified into three categories:
1. Full Range - defined by ANSI as ia fuse capable of
interrupting all currents from the maximum rated interrupting current down to the minimum continuous current that causes melting of the fusible element(s), when the fuse is applied at the maximum ambient temperature specified by the
manufacturer.@ It is able to interrupt any normal 60 cycle
current that will melt its element.
2. General Purpose - defined by ANSI C37.40 as ia fuse capable of interrupting all currents from the maximum rated interrupting current down to the current that causes melting of the fusible element in one hour.@ Not all currents fall within this range. It is possible to receive an overcurrent lower than the value given by the one hour criterion.
3. Back-up - defined by ANSI C37.40 as ia fuse capable of interrupting all currents from the maximum rated interrupting current down to the rated minimum interrupting current.@ The minimum rated interrupting current is the lowest current that the fuse will be able to clear properly. This creates a need to place a low current interrupting device in series with the back-up rated fuse.
