60A 58vdc (48vdc) MEGA Fuse. Do they exist??

Need a 60a mega fuse for 48vdc system but can find them anywhere. Meant for Victron SSCC 150/45. Can't find any 70Vdc ones either. Anyone know where in the US these unicorns can be procured?

@Duswami

You can switch to a MIDI fuse holder instead of MEGA.

Amazon has 60A in those. You dont have to use the link I have attached, it is just an quick example.

You ended up in a weird place in your system sizing between the mppt size and the lynx.

Upgrade the mppt? ;)

Given that the mppt has an internal fuse, could the OP use 35mm battery cable, and then rate the fuse to suit that?

Well, sorta. It's a small system. 370w panels in 2s2p, so the total Amps are low(er).

Could I use a 60a 70v fuse instead?

try digi-key: https://www.digikey.com/en/products/detail/littelfuse-inc/0998060-UX-2M8/15297310

Edit: oups..these 60A versions do sell in batches starting 500pcs, as it seems.....but you can find them on ebay...search for littelfuse brand, like here

Hello. Please try this amazon link. I had tried this and the 58V fuses are Ok.

Spot on!!!! Unfortunately...they don't ship to the USA and nothing showing that would ship to the US. Bummer! But, thank you for trying :)
