IR 50kA Agency Information E-Rated Medium Voltage Fuses Meets E requirements per ANSI C37.46, and General Purpose requirements per ANSI C37.40 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. Cooper Bussmann medium
voltage fuses provide general purpose protection and are capable of interrupting fault currents up to 50kA RMS sym.
• Clip-Lock Double Barrel Fuse Design.
• The filament wound, glass epoxy fuse tube provides moisture protection for the fuse. This makes Cooper Bussmann medium voltage fuses suitable for both indoor and outdoor application outdoor applications require installation inside an appropriate enclosure .
• Open Fuse Indication. Indicator travel distance is 16mm.
• Operating Frequency 50/60Hz
• Dimensional Data See page
• Performance Curves See pages

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.
