Why is part number 44044-027-61 needed when ordering 150E and 175E fuses for a HVL/cc switch originally equipped with 15E -100E fuses?

Issue:
What is needed 44044-027-61 to convert a HVL switch using 50E fuses to 150E and 175E fuses?

Product Line:
HVL/cc Switches

Environment:
Installation

Cause:
Upsizing

Resolution:
For the 15kV, HVL/cc switch, when going above a 100E fuse the fuse clips are a different material and the fuses mount in the clips slightly differently. The 44044-027-61 part is essential for the higher temperature rise the larger amperage fuses produce.
Part number 44044-027-61 needs to be forced to Plant.
