Go Power! FBL-400 Class T 400 Amp Fuse with Block , black

Exactly what I needed for my Solar setup. The holder was exactly what I was hoping for with the hex key setup to tighten down on the wire and the cover. I was able to get it setup without any issues and am very happy with the build quality.

This is a great fuse block. It is a Deltec Co CFB2-400 fuse block/fuse with a Go Power sticker on it. Very robust construction and does what it is supposed to due. If you ever need to replace the fuse, it's a Deltec T-400 fuse (might be easier to source searching that way). Difficult to install 4/0 cable if the cable end is mushroomed from cutting. Easy trick. Cut the required amount of cable covering (insulation), but do not remove. Ring it again at half the distance and removed that end part of the cable insulation. Side the remaining half (1/4" or so) to the end of the bare cable (leaving just the tip of the cable exposed. Helps if you've lubed it with dielectric grease (which you shold be using anyway). Now the cable end is compressed enough to fit (if not, squish it a bit wit your fingers, the insulation will help it regain its proper shape/size). Push the cable in and while being careful not to let it slip out, cut and remove the remaining insulation ring. Push in the rest of the way and tighten. Hope that makes sense.

We were on vacation when the solar power system in our camper failed and we weren’t able to power any of the larger appliances like the air conditioner. Thankfully, Amazon had what we needed in this fuse and holder, so we were able to get this shipped to our resort where I quickly installed it so that our vacation wasn’t ruined!A note to buyers, if you are replacing a similar unit that has blown out, you may just think that you need to buy only the fuse. However, in our case, we needed a new fuse AND holder because the holder has been designed to melt at the base of the connectors when a fuse fails for further electrical protection.Had we only bought the fuse without the holder, we wouldn’t have had what we needed to save our vacation and we would have had to return home early.That said, unscrew the pld fuse holder assembly and examine the bottom, if you see melted metal and plastic at the base of the connectors, then you need a new fuse AND holder in order to get your system up and running again.I don’t recall much in the way of directions being provided with this product. Needless to say, if you are using one of these already, then it’s pushing a dangerous level of power through it, so be sure to disconnect all batteries, inverters, and chargers in your solar system before you replace. Use a multimeter (properly rated for the application) to test all the lines coming in and out of the fuse holder in order to make sure that no current is passing through before you make a potentially lethal mistake!

It’s very heavy duty and well built, I use it with my Victron multi plus 2 inverter that I installed on my Grand design Reflection 303RLS, it works great and haven’t had any issues, going on 2 years so far.

Easy to setup/install. I had to assemble it, the parts were loose in the box. I used a little lock tight to ensure the cables stayed in place. I only wish you could use cable lugs with it instead of bare cable. 4/0 cable fits snug, but worked without issue - just in case anyone was wondering...

Does what it is supposed to do!

This is a heavy-duty fuse and fuse holder for 0000 gauge wire. appears to be well made and should last. The only issue I had was getting to 0000 gauge wire into the ends. A tapered opening would have made it easier to insert the wire. I highly recommend this

No instructions, specs, like max'min size .. lug size.. no manual no nothing
