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: — 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
