CURRENT LIMITING CONSTRUCTION: • Silver element in a double concentric helical configuration • Silica filler • Silver plated copper terminals and endcaps • Filament wound, glass epoxy fuse tube FEATURES: • General Purpose Fuses. Bussmann’s medium voltage fuses provide general purpose protection and are capable of interrupting fault currents up to 50,000A RMS sym. • Clip-Lock Double Barrel Fuse Design. • Indoor and Outdoor Usage. The filament wound, glass epoxy fuse tube provides UV and moisture protection for the fuse. This makes Bussmann’s medium voltage fuses suitable for both indoor and outdoor applications. • Open Fuse Indication. Indicator travel distance is 16mm. • Operating Frequency: 50/60 Hz Current-limiting medium voltage fuses are classified into three categories: Full Range - defined by ANSI as “a 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. General Purpose - defined by ANSI C37.40 as “a 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. Back-up - defined by ANSI C37.40 as “a 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.
