Protection
Products listed in table "UL508 SCCR FUSES TABLE " are suitable for use on a circuit capable of delivering not more than 100,000
A rms Symmetrical Amperes, 600 Volts maximum when protected by fuses.
Use fuses only
According to UL508, test at 100.000A were carried out with class J fuses rated xxxA (refer to table "SCCR fuse protection table" to
details of the current size fuses for the fuse).
After a shortcircuit the functioning of the device is not guaranteed.
To guarantee the functioning of the device after the short circuit, it is recommend the use of extra rapid fuses as in table "EXTRARAPID
FUSES".
ATTENZIONE
: The opening of the branch-circuit protective device may be an indication that a fault has been interrupted. To reduce
the risk of fire or electric shock, current-carrying parts and other components of the device should be examined and replaced if
damaged. If burnout of the device occurs, the complete device must be replaced or equivalent.
