Description This product can be used in indoor AC 50Hz and
rated voltage12kV system. Used together with other switch
facilities such as loading switches or vacuum contactors it can
protect high-voltage transformers and other electric facilities
from overloading and short circuit. An optional low-voltage
sensitive switch is available. When the fuse acts, the striker of
the fuse triggers the switch to signal. Model and meaning

Interrupting ratingsNotes: 1. The 8.3 kV 80 A and 100 A ratings
have been tested and approved for application at 9. 9 kV. 2.
The 15.5 kV. 80 A through 125 A ratings have been tested and
approved for application at 17.2 kV.The maximum interrupting rating
for the 15.5 kV fuse, 80 A through 125 A at 17.2 kV is 43 kA. For
the 23 kV, 250 A fuse (parallel 125 A) the maximum interrupting
rating is 12 kA.Table 3. Dimensional information Application
