Medium Voltage Fuses E-rated fuses: CL-14 ECL155 Specifications Description: E-rated medium voltage, current-limiting fuses for transformer and feeder protection. Construction: Filament wound, glass epoxy fuse tube, with silica filler, and silver-plated copper terminals and endcaps containing a silver element in a double concentric helical configuration. Ratings: Volts: -- 15.5kV Amps: -- 10-300A IR: -- 63kA Sym. (10-200A) -- 50kA Sym. (250-300A) Agency Information: Meets E requirements per ANSI C37.46, Meets General Purpose requirements per ANSI C37.40. Features and Benefits * Clip-lock double barrel fuse design assures positive installation * The filament wound, glass epoxy fuse tube provides UV and moisture protection, making these medium voltage fuses suitable for both indoor and outdoor applications * Open fuse indication (indicator travel distance is 16mm) easily integrates into automation schemes * 50/60 Hz operating frequency make these fuses applicable world-wide * * * * Typical Applications 15.0 kV Transformer Primary Protection 15.0 kV Feeder Circuit Protection 15.0 kV Voltage Switches 15.0 kV Metal-enclosed Switchgear 3. 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.

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. 2. 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.
