<True. There are no current limiting breakers, so a fuse is the only
option.>


Eric,

What about the hundreds of systems out there using Trace DC250 disconnects
(Heinemann breakers) with no current limiting fuse.
I always used to use Class RK5, or Class T fuses until Trace came out with
their disconnect box using the dc rated Heinemann breaker. They said that
these breakers met code and that we no longer needed current limiting fuses.
