Note:
To order a 15.5kV fuse that will fit in an 8.3kV wet-well fuseholder, replace the 7th character (“0”) in the catalog number with a “2” (example: HTSX242050).

SX Fuse Ordering Information
To order the proper fuse for a particular application, first determine the correct fuse voltage and current rating using
the published performance data (
page H-105
). Then refer to the chart below to determine the appropriate catalog number.
Alternatively, fuse selection can be determined using the accompanying charts on
pages H-106–H-107
.
When replacing the obsolete AB Chance SL fuse with a Hi-Tech

Trans-Guard
®
SX fuse, it is important to recognize that the SX fuse designs
should not be used on distribution systems where the primary line-to-line voltage
exceeds the rated maximum voltage of the fuse as shown in the chart to the right:
This should be considered when choosing a proper replacement for the AB Chance
SL fuse as they were, in some cases, used on systems having line-to-line voltages
greater than that of the current-limiting fuse component of the assembly.
Again, when choosing the appropriate Hi-Tech SX fuse to replace the AB
Chance SL fuse, care must be taken to ensure that the rated maximum voltage
of the SX fuse exceeds the system line-to-line voltage. The only exception to this
requirement is when all the transformers that are downstream from the switches
where the SX fuses are to be installed are GndY-GndY connected with less than
50% delta connected secondary load. In that case, a fuse having a rated maximum
voltage exceeding the system line-to-neutral voltage may be used.
