Am Sicherungshalter ist absolut nichts zu bemängeln. Er ist unglaublich massiv und gut gebaut – Blue Sea halt. Dafür gäbe es 5 Sterne. Leider stimmt das Bild nicht und die Bezeichnung von 320 A ist blödsinnig. Viele Rezensenten haben sich offenbar überhaupt nicht informiert, deshalb hier ein paar Klarstellungen:- Das Bild entspricht nicht dem Produkt. Erhalten habe ich die neuere Version mit den zwei gelben Klammern.- Natürlich ist keine 320 A Sicherung enthalten. Wer sich halbwegs informiert hat weiß, dass eine Class T Sicherung genauso viel kostet wie dieser Sicherungshalter. Ja, sie sollten das Bild ändern, aber auf dem Bild ist auch eine 400 A Sicherung abgebildet, das sollte schon stutzig machen. Wer sich so wenig mit der Materie befasst hat, sollte vielleicht lieber nicht solche Sicherungen installieren.- Es muss nichts aufgebohrt werden. Es gibt verschiedene Größen an Sicherungen und dieser Halter ist für Sicherungen von 225 - 400 A. Diese passen wunderbar. Wer kleinere Sicherungen braucht, kauft das Modell für 110 - 200 A. Sollte man vielleicht im Titel und in der Produktbeschreibung explizit erwähnen. Man kann die kleinere Sicherung aber tatsächlich aufbohren und im "großen" Halter installieren. Könnte interessant sein, wenn man absehbar sein System vergrößern will und dann eine Sicherung größer als 200 A braucht.

Mounted this inside the engine bay of my 2024 Chevy Silverado 3500. I made a 3D printed ASA filament holder for this fuse hose hold and it works great!

This is one beefy piece of hardware. It took a lot of looking on the Blue Sea website to make sure this block was the right one for the fuse I was buying. They have a mechanical drawing, but the drawing is missing the most important dimensions: The post spacing! I included an updated drawing showing the post spacing and lug size. I hope this helps the next guy.

We buy this product quite a bit and it can be very hard to find with limited supply in the retail stores, and it’s always available from this vendor and arrives very quickly never a functionality problem

Very well made block. Listing is exceptionally misleading.Lists as a 160a, and shows a fuse in the pictures, does not include the fuse.Says only one time at the bottom of the description that fuse is not included, which I and several others completely missed.One star for misleading listing practices.Shame because the block is well made and fancier than your typical block. Will not do business with crimpsupply.com in the future.

I tried now two different T fuses from two different brands, neither fit. The post on the block are 1/4-1/2 inch to close and the fuses won’t fit onto the holes. The block does appear very well built and strong. I will need to order a new class t fuse for it to finish install.

JUST a word to the wise: APPARANTLY there are different sizes of "class-T" fuses. i had no idea. honestly, i never heard of a class-T fuse before a few months ago. i got some Mersen 200A and 400A fuses for my solar setup. the 400A fit this JUST FINE! the 200A... well... needed some "modification". the holes were too small and too close together to fit this fuse holder. i had to drill the mounting holes in the fuses out to fit. in my inexperience, i mistakenly thought all class-T fuses were, well, standardized in size. they. are. not.

I was really surprised by the size of this fuse holder. It’s what I wanted so not a big deal but I would suggest looking at the dimensions if you have space issues.

when you read that this is heavy duty, that doesn't do it justice. It is massive and up to the task of providing a way to mount the 400 Amp fuse I needed. I am surprised that product information is so sparse. The 3/8" studs and bolts are 1-7/8" on center for the Fuse and the cover easy accomodates up to #4/0 cable lugs. The fuse probably should not be shown, since it doesn't come with it. It can accept (like it shows 225 to 400 Amps). I previously installed a cheaper fuse block, which was not up to the task... there is no substitute for quality and when protecting your RV, peace of mind is king.

Needed a really beefy fuse holder for my boat battery bank / inverter . This product exceeded my expectations, was delivered promptly and met the product description in every one.
