EBI055 & ECL055 E-rated Fuses: CL-14 & Bolt-In

  
Description: E-rated medium voltage, current-limiting fuses for transformer and feeder protection.

Construction:
• Silver element in a double concentric helical configuration
• Silica filler
• Silver plated copper terminals and endcaps
• Filament wound, glass epoxy fuse tube

Ratings:
Volts: 5.5kV
Amps: 10-900A
IR: 63kA Sym. Max

Agency Information: Meets E requirements per ANSI C37.46, Meets General Purpose requirements per ANSI C37.40.

Features and Benefits
• General Purpose Fuses. Bussmann’s medium voltage fuses provide general purpose protection and are capable of interrupting fault currents up to 63,000A RMS sym.
• Clip-lock and bolt-in style available in double and triple barrel fuse designs.
• 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
• Performance Curves.Typical Applications
• 5.0kV Transformer Primary Protection
• 5.0kV Feeder Circuit Protection
• 5.0kV Voltage Switches
• 5.0kV Metal-enclosed Switchgear

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.
