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…

Product itself is good.The used very good one I purchased was not worth the discounted price.Busbar had been filed away, fuse mounting studs cut and filed down, some slight bending of the terminal mount side. It won’t properly hold a fuse as the posts are too short for the nut to securely fasten it. Poor condition would have been a better description.The other one I purchased is great!

Used this in our cruising sailboat as a combination buss bar and fuse rail for three house battery charging sources.The outputs from a solar charge controller, a shore power/generator source and an ACR in the alternator charging circuit were combined and connected to our 400Ah house battery bank.A neat way to combine and fuse several high current circuits.The MRBF fuses are relatively expensive compared with conventional fuses but that is offset by the reduction in parts count to some extent. Definitely worth spending the extra for the compact and tidy result.

Blue Sea products are excellent quality.

Why did you pick this product vs others?:It's the highest rated seller for this product. Genuine Eaton part. Photos show it having fuses but it does not come with fuses.Safety:These should be standard on all electric carts and scooters. These should also be standard on anything with long runs of battery cable.

I like this device and its designed well with reasonable utility. I use a variety of blue sea electrical related items on my offroad truck. Quality and design are good.

The Blue Sea Systems 5191 Fuse Block Terminal has been nothing short of a revelation for my power management setup. I invested in this brilliant solution to seamlessly integrate my Dometic RTX2000 air conditioner into my Lynx distributor by Victron.The challenge with the Lynx distributor was its limited available slots, necessitating the addition of another Lynx—an expensive and space-consuming proposition. The Blue Sea Systems fuse block terminal provided an elegant and straightforward solution. By attaching it to the end of the Lynx and securely fastening it with a simple bolt-down mechanism, I was able to connect the air conditioner to the Victron system.This small yet critical addition allowed me to not only connect the air conditioner but also monitor its current, draw, and amperage. In the past, the air conditioner was directly linked to the battery, leaving me guessing about its power consumption, which was far from ideal.It's essential to note that when installing the Blue Sea Systems 5191 Fuse Block Terminal, make sure you don't over-tighten the fasteners. Refer to the manufacturer's torque specifications to ensure a secure yet safe installation.In a nutshell, the Blue Sea Systems 5191 Fuse Block Terminal is a must-have addition for anyone aiming to optimize their power management system. It's a versatile, user-friendly solution that resolves common power distribution challenges. I wholeheartedly recommend this product to fellow enthusiasts who wish to take the guesswork out of power monitoring and improve energy efficiency. It's a true game-changer, delivering on its promises and ensuring a more streamlined and efficient power setup, with a vital caution for installation.
