Blue Sea Systems Class T Fuse Blocks

Q: The description and reviews are confusing. The specs say "push to reset operation", but I see only replaceable fuses. Which is correct?

mine looks like a hard line fuse/non reset

Q: Dose the fuse come with the block or do I order a 400amp sep.?

Fuses are sold separately. The Blue Sea 400A fuse is on amazon - search for B000MMH1JO. Hope this helps.

Q: is there a 400 amp fuse in this block when it comes ?

The fuse is sold separately and can be from 225 amp to 400 amp.

Q: Does this product come with fuses?

No it does not and for good reason. There is a wide range of fuses that can be used in this fuse block and they run about $35 per fuse. Good product
