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 Series plug fuses offer similar short circuit protec-
tion to the W Series plug fuses. In addition, the T and TL Series 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 Series
plug fuses (Data Sheet: 1035) utilize a loaded link construction and
provide medium-duty performance. The T Series plug fuses (Data
Sheet: 1034) utilize the advanced dual-element design for heavy-duty
performance. This construction makes the T Series the preferred
selection. For additional information, please see the applicable Data
Sheets.
