Table 3.8 presents the short circuit capacity, Standard Fault, of the
power supply (symmetric Arms) at which the SSW-06 can be installed,
provided that protected by means of regular fuses or circuit breakers,
used in the UL tests.

Table 3.8
- Short circuit capacity standard connection - UL Standard Fault
The fuses in table 3.8 used in the SSW-06 UL tests are of the ultra-
fast (aR) type, which also reduce the risk of SCRs being burned by
over current transients.
Table 3.9, presents the short circuit capacity, High Fault, of the power
supply (symmetric Arms) at which the SSW-06 can be installed within
a closed panel, standard connection, provided that protected by means
of circuit breakers, used in the UL tests
.
