3. Fusible Link
OM·1135
Fig. 15-9
If current increases beyond specified
amperage, fusible metal melts and
the circuit is broken, thus protecting
cable and electrical equipment from
burning.

amperes.
CAUTION:
a. When replacing fusible link, be sure
to use one with the specified rating.
b. Blown fusible link is caused by
short circuit in the source of elec-
tricity circuit or large amperage
circuit, so certain check of cause
and/or repair is necessary.
