I've got a couple of circuits which need fuses lower than 100A, and I'd like to connect them to the positive and negative busbars inside my Lynx distributor. Mega fuses fit perfectly (as the Lynx dimensions are intended for those) but 48V Mega fuses are all greater than 100A.
So I'm looking at MRBF fuses. The Lynx housing has enough vertical space to mount them, I'll just need to replace the bolts with longer ones.
The other issue with MRBF fuses is voltage rating - I'll be charging my battery to a max. of 57.6V, which is below the fuse's max rating of 58V (can interrupt 2,000A at 58V). So that seems OK. However MRBF product info only mentions 12V, 24V and 42V systems. Perhaps they're avoiding mentioning 48V systems because some of those charge their battery above 58V, which is not the case for me? I've also got a Class T fuse at the battery.
