When choosing a fuse you should consider two things.
1. The first is the system voltage.
2. The second is the amperage rating of the system, always match the
fuse to the wire/cable amperage rating and the load. The load amperage
rating should not exceed the amp capacity of the wire or cable and the
components such as the Motor and Controller.
T fuses have a high arc interrupt rating and are specially designed to
and smother a direct current arc when the fuse blows.
opens the circuit and can help prevent catastrophic battery damage.
Class T fuse should be placed as close to the battery(s) as
running into and out of your batteries should go through
Class T fuse.
d.c. voltage ratings on these Class T JJN fuses are:
15 to 100 amp fuses = 300 volts d.c.
to 600 amp fuses = 160 volts d.c.
to 1200 amp fuses = 170 volts d.c.
fuses are the same dimensions as the JJN and have a 125 volt d.c.
fuses are the same dimensions as the JJN and JLLN and have a
volt d.c. rating.
T fuses have an Arc Interrupt Rating Current
of 20,000 amps D.C. and
installations usually require a Class T fuse.
