W-15, W-20, W-25, and W-30 plug fuses
obsoleted suggest replacing with either
T-(amp) or TL-(amp) plug fuses
Both the T and TL Bussmann series plug
fuses offer similar short-circuit protection to
the W plug fuses. In addition, the T and TL
plug fuses offer time-delay performance for
overload currents (typically between one and
six times the rated current of the fuse). For
most applications, this feature is preferred to
allow harmless inrush currents to pass without
causing the fuse to open unnecessarily. The TL
plug fuses (data sheet No. 1035) utilize a loaded
link construction and provide medium-duty
performance. The T plug fuses (data sheet No.
1034) utilize the advanced dual-element design
for heavy-duty performance. This construction
makes the T plug fuses the preferred selection.
For additional information, please see the
applicable data sheets.
Features:
• For lighting, heating or other circuits that do
not contain electric motors
• Edison base size
• These fuses thread into fuse receptacles or
Bussmann series box cover units
• The general purpose (W) fuse has no
time-delay feature and should not be used in
circuits that contain motors
