Yes I have 5 of them in use (2 for this exact purpose). They are really the best I have ever seen - some nice construction work. My opinion of my previous favorite dropped due to poor case material choices - degraded over time in that location. Based on materials I think these will hold up much better - but I don't have the accumulated time yet to be totally sure. These are nicer in other ways - fully flash shielded, great parallel terminal contact area & sprung pressure, easy access to fuse and connectors, easy labeling.

(and yes these uninstalled ones are very dusty)

Those are sweet! I'm going to get/use some of these and see how the perform.
When running an 044 pump, in the rear of the car, I've sen a couple blade style fuse holders fail and leave the vehicles stranded. Those fuel pumps draw a bunch of current continuously and something better is needed.

Thank you, Alan, for sharing this!

Here you can see that the sprung terminal plate is removable - and you can see the parallel terminal plate - the spring is quite high pressure. The sprung plate provides some contact path most reliably just though the spring section - but mainly it ensures the fuse blade makes full contact on the other side over the full area of the blade - really the full area of the blade - and these are Much bigger blades than ATO/ATC fuses. If you've never seen an ATX (Maxi) fuse - see below where you can appreciate it is a much more capable form factor. The maxi fuse blades are thicker at 0.85mm Vs 0.68mm and are 12.9mm long x 8mm wide while ATO/ATC are 6.6 mm long and 5.38mm, wide at their widest part - so well less than 1/3 the contact area at best, In practice the actual contact made is usually much smaller than that even even under perfect/new equipment conditions due to the mini claw design of most fuse holders.
