Fuse Types: Maxi vs ANL, inline vs block

[Cdn_bacon]

I'm installing a new 30A 3 bank battery charger and the manual calls for a 40A fuse (min) and 50A fuse (max) between the charger and the batteries. I was going to grab a maxi fuse but then discovered ANL fuses.

I'm hoping someone can explain to me the differences between a Bluesea MAXI fuse and an ANL fuse? Spefiically, which is best for my application. One step further, if it's a Maxi, why would I want to get a fuse block instead of an inline fuse holder?

If I'm using the BlueSea Circuit Wizard right, then I believe it's telling me that a 50A fuse is optimal however 40A is acceptable. By saying that, I assume I would use 30A for the CCA rating on a main branch since the max the charger can put out is 30A to a single battery?

I believe MAXI fuses are rated to interrupt 1000A and ANL fuses are rated to interrupt 6000A. Assuming you're installing the fuse at the battery to protect the wiring in the event of a wiring short or component fault in the charger, I'd go with the ANL since most batteries can put out >1000A into a short circuit, which could potentially resulting in an arcing fuse.
