Hello i am trying to find some one that sell the mega fuse in 500amp 48v, i can find the 32v fuses everywhere but can't really find anyone that sells the high amp fuses for 48v, i have found some 300amp ones but i am trying to fuse an electric motor and need the higher amps. Does anyone know of a place that sells teh 48v 500amp mega fuses?

it seems like they make some Class T 500amp fuses but it looks like you have to call them for a price. its probably a special order from the looks of it:

i have no idea personally. the spacing is the same between the poles of those fuses, but that class t one is thicc. not sure if it would fit?
looks like littelfuse makes two different 48v fuses and the sf56 is the one that is impossible to find but the sf51 seems to be searchable with 0998500
Class T’s are too thick. But I was able to fit 3 (vs 4) with some modification.
I found a supplier of the sf51 here
the sf56 are impossible to find
Both are for 70v systems so our 58v max on lifepo4 is within tolerance.
wow, those sf51's are only $11 bucks too!
11 bucks vs 30 per fuse from here https://signaturesolar.com/victron-mega-fuse-125a-58v-for-48v-products-1-pc/
I don’t know his application, but the 350A or greater ones are for short-circuit protection only, not over-current protection. Also not UL.
electric motor which has the possibility of pulling 650a and my battery bank do have 300a relay bms to feed the motor.
Can you run two cables to your motor with a 250 amp fuse on each cable?
i didnt know that either. thanks!
I am running a single 500a fuse and 4/0 over like a 4inch run to the motor controller which then convert that 48vdc to 3 phase AC and that requires 2awg and that will be my "long run" of like 3 feet
