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.

Table 1. Electrical ratings and characteristics
| Fuse type | Maximum interrupting current |
| 8.3 kV-15.5 kV back up"C" rated | 50,000 Arms symmetrical |
| 17.2 kV back up"C" rated | 43,000 Arms symmetrical |
| 23 kV backup"C" rated | 31,000 Arms symmetrical |
| 38 kV backup "C" rated | 50,000 Arms symmetrical |
A: 23 kV, 150 A fuse is rated to 50,000 Arms symmetrical.
B: 38 kV, 200 A fuse is rated to 26,000 Arms symmetrical due to
test lab limitations.
Table 2. Interrupting ratings
Notes: 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.
