<p>We've used the inline glass fuses for metering and battery fan
applications for 20 years without trouble. I certainly wouldn't
use them over 5 amps though. I actually tested these inline fuses
on a 144 vdc vehicle battery bank once, and they blew without
arcing or burning. Of Course my name is not UL. However, this is
also the fuse that comes with Trimetric, Victron E-meters, and the
Zephyr power vents, currently. Also, glass fuses were used in many
DC power centers back in the day, so they have a long and proven
track record in the 48 v dc solar industry for low amp
applications.</p>
<p>I found a standard fuse holder from Grainger that is rated for
300 Vdc. The regular AGC fuse does not list a DC rating, which is
odd, since it is used for DC all the time. The ABC fuses are
listed to 125 vdc and are fast acting. <br>

<div>Hello Wrenches,<br>
<br>
I'm looking for in line fuse and fuse holders for a 48 VDC
systems in the 1 - 4 Amp rating. The systems can go 67 VDC.
FRN-R fuses have this rating but are slow blow, 8 seconds at
500% current rating.
<br>
<br>
Is a glass fuse and in line fuse holder, listed for this
voltage and amperage, available anywhere? It seem that the
default is to use 250 VAC glass fuses and holders, which seems
like a questionable practice to me.<br>
