FBL-400 Class T 400 Amp Fuse with Block , black Review: Needed not just a fuse, our holder was melted underneath! This saved our vacation! - 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, desertcart 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! Review: Great quality and working fantastic. - 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. ## Features - Inverter Class T slow blow inverter fuse with holder 400 amp - Semi conductor fuse - Guarenteed to terminate power when blown - Specifically made for use with inverters ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00153CXKQ | | Best Sellers Rank | #210,336 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #397 in Automotive Fuses #695 in Fuses | | Brand Name | Go Power | | Color | black | | Customer Reviews | 4.7 4.7 out of 5 stars (182) | | Global Trade Identification Number | 00839085000250 | | Included Components | Fuse Block & Fuse | | Item Dimensions | 9 x 4 x 4 inches | | Item Weight | 1 Pounds | | Manufacturer | Go Power! | | Material Type | Polyester | | Maximum Current | 400 Amps | | Model | FBL-400 | | Mounting Type | Bolt-On Mount | | UPC | 839085000250 | | Voltage | 240 Volts | | Warranty Description | 1 | ## Product Details - **AC Adapter Current:** 400 Amps - **Brand:** Go Power - **Item dimensions L x W x H:** 9 x 4 x 4 inches - **Material:** Polyester - **Voltage:** 240 Volts ## Images ![FBL-400 Class T 400 Amp Fuse with Block , black - Image 1](https://m.media-amazon.com/images/I/71lj+Ft84KL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Needed not just a fuse, our holder was melted underneath!

I was able to get it setup without any issues and am very happy with the build quality. ### ⭐⭐⭐⭐⭐ Great Fuse Block *by 2***S on November 25, 2015* 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. ## Frequently Bought Together - Go Power!
