7721 Fuse Block Safety SEA/AMG

Used for my 92 cummins. Worked perfect for replacing the terrible fusable link.

Great for my solar, car audio and boating needs, what a well built fuse holder. Highly Recommend!

Bought this after a super cheap fuse holder I had arced out where I had it mounted in my Jeeps engine bay after doing a full battery cable upgrade. The cheap fuse holder lasted a few years but after finding it half melted and seeing that the stud (just a bolt in epoxy resin) had arced out on my inner fender well because the plastic was so thin I immediately counted my blessings it didn't burn my vehicle to the ground and jumped on here to get a Blue Sea Systems set up. I went with this one as it seemed to be the most robust and I loved that the fuse is encased with a weather tight seal too. Thing is primo, but you do pay for it. Both in unit costs + specific fuses but after what I dealt with I don't even care for the peace of mind. EDIT AFTER LOTS OF MILES OF OFFROADING: Unit is holding up even better than I expected. The sealed off waterproof section where the fuse goes is the best feature to this thing, it's kept out all the elements which is great as my Jeep has hood spacers which lets in more dust than stock hoods do and it sees lots and lots of miles of offroading trails and dirt roads. Blue Sea products have yet to let me down with anything from them I've put in my rig.

Blue Sea makes excellent marine grade electrical components. Mainly writing review to note origin of Mexico on 5/13/2025 as it really irritates me when Amazooon neglects to list this information. The rear of package states "Designed in Bellingham, WA USA" And "Assembled in Mexico"

Worked for my 200 amp alternator upgrade, 87 Bronco 5.0

This fuse block is really nice and I'm really happy with it to replace my cheap ALN fuse block. However, the only thing that I could gripe about is they don't/didn't include the screw for the spare fuse. Seems like a very nice, high quality unit either way.

This fuse block is well made. The base is made from a stout glass-filled material that is ultra strong. The cover fits perfectly and is sealed with an o-ring that makes it water resistant and explosion proof. The double opposing clips secure the terminal cover so that it absolutely cannot come off, no matter the application. Rough roads? No problem. This MEGA fuse is very heavy duty and reliable. Buy the correct amperage fuse and it will serve you well for decades. Don't make the mistake of buying a cheap fuse block that needs to be replaced through faulty performance. Buy this first. It costs a little more, but certainly costs less than buying a cheap one first! You will not regret it. Its the best.

nice fuse blocks for my solar. was easy to work with and saves stacking wires on one post

Good but too expensive

Excelente portafusibles, buen tamaño y con protección

Great for the application I intend to use it for

I orderd 3 blocks fuses that appeared to fit. but they did not fit. I will return these blocks I had to order new fuse blocks for MIDI fuses
