Primary Fuse Kit
The primary fuse kit includes a two-pole class CC fuse block,
instructions, and all associated mounting and wiring hardware.
Fuses are not included. When installed, the primary fuse kit
will add a maximum of 11/16 inch to the transformer depth
and 1-15/16 inches to the transformer height.

Technical Data and Specifications
Insulation System and Temperature Rise
Industry standards classify insulation systems and rise as
shown below:
Insulation System Classification
The design life of transformers having different insulation
systems is the same—the lower-temperature systems are
designed for the same life as the higher-temperature systems.
Series-Multiple Windings
Series-multiple windings consist of two similar coils in each
winding that can be connected in series or parallel (multiple).
Transformers with series-multiple windings are designated with
an “x” or “/” between the voltage ratings, such as voltages of
“120/240” or “240 x 480.” If the series-multiple winding is
designated by an “x,” the winding can be connected only
for a series or parallel. With the “/” designation, a mid-point
also becomes available in addition to the series or parallel
connection. As an example, a 120 x 240 winding can be
connected for either 120 (parallel) or 240 (series), but a
120/240 winding can be connected for 120 (parallel),
240 (series) or 240 with a 120 mid-point.
