Highest Quality
I have done several DIY solar projects. For safety, I always put a proper sized fuse at the battery. With this MRBF Terminal Fuse Block, I can simply mount the fuse right to the battery post. It is simple to mount, small and very high quality. I only needed a single fuse block, but they had a super special where the dual fuse block was way less expensive then a single fuse block. So I bought the double. This is a very well designed piece if equipment. The build quality is superb and it is made for harsh salt water environments.

Schlanke Installation
Sehr gutes Produkt, ermöglicht eine schlanke Elektroinstallation mit dem Nachteil, daß die Sicherungen ihren Preis haben. Für mich aber trotzdem angenehmer, als eine extra MEGAfuse-Box plus Kabel einzubauen.

Dubbio sull’originalità del prodotto.
Arrivato in una bustina trasparente anonima. Non posso escludere che si tratti di merce non originale Blue Sea System

Great Quality, high price.
This worked great on my 48v battery bank of 8 12v 280 AH ecoworthy batteries. Save so much wire and headaches with the bussbars. Note: do not get the cheaper bojack fuses as they have not been reliable in my experience. I did not like spending $18 for the better fuse but had to anyway…
