I love the Lynx distributor with its mega fuse slots.
How do you fuse charge controlers if the smallest mega fuse 48v is 125amp ? for a 45 to 85a in 48v ?
thanks

Lynx distributor & mega fuses
Hi @Herve RV Nizard,
for smaller rated fuses I use Littlefuse, which are available either in 32V or 70V with the smallest at 60A.
Thanks
@Stefanie . are they exactly the same size as the mega fuses ? to fit in the lynx distributor ?
Problem...I can't find any seller for the 70v version of Littelfuse Mega fuses. Anyone else have any luck?
Not sure if you are still looking but have found these guys in Australia who will ship internationally, have not tried them but may be worth a go.

It would be really nice if Victron extended their range of 48V mega fuses to include lower Amp rated fuses.
Example being the challenge trying to connect an MPPT to a Lynx busbar with both the correct fuse per the MPPT manual requirements and a suitable fuse voltage rating.
Also the Littlefuse 70V range have short circuit rating of 2500A which meets the requirements of a single Pylontech US5000. Much neater than adding NH00 fuse holders to the system.
Just a reminder that the amp rating of the fuse is primarily to protect the cable, not the device.
I'm aware of that but the installation manual for the solar charge controllers has some very specific instructions on fuses sizes.
And Victron do not supply a MEGA fuse suitable for a 48V system with a rating less than 125A. Which means you potentially have to mix MEGA and MIDI fuses which is messy.
As long as you protect the cable, that is, that the fuse is rated at or below the maximum current rating of the cable, you'll be fine. The MPPT's have an internal fuse albeit if they blow, you'll need to take it in for service as it's not a part that can be changed by the user.
@Atebee you can always use the littelfuse which comes in the flavours your after and fit the Lynx distro
i found this company in the UK not sure where you are but you can get more flavours of fuses for a fraction of the price high voltage rating too hope this helps just double check the measurements but mine fit my Lynx without issue
Mega-Fuse 58V down to 40A:
