This review is for the Relaxweex brand terminal block and 150 amp fuse combo.The terminal fuse block is a clone of the terminal fuse blocks from South Bend Components and Blue Sea Systems. I use these to individually fuse the connection to each of my 12v batteries in a 12volt battery bank.I wouldn’t use a clone like this on a 48 volt system, but for a small DIY 12 volt solar generator, this will work fine.The included 150 amp fuse is generic, so I wouldn’t recommend it for anything critical. I’m keeping it as a backup.

I already have a fuse for this so I just got the holder this time. I have also bought name brand MRBFs before with their fuse included for just a little bit more than this holder alone. It does work fine and has the same materials as the name brand with a little bit poorer finish. I don't think it matters, it's nickel plated and same solid insulation material. It has the same stud size and full thickness bar as the name brand but I think they could lower the price a bit more to make it a shopper's choice.
