Changed title to be more appropriate, added clarification.

| Jul 4, 2021 at 22:50 | comment | added | Hackstaar | @Passerby the fuse I am using is rated for 125V DC. I have done the spark-gap and arc-sustenance calculations and estimated that the fuse should be able to easily support over 500VAC. I will, of course, contact the manufacturer when I go into production and get them to make a datasheet for the new fuse with well-defined maximum ratings. | |
| Jul 4, 2021 at 22:47 | comment | added | Hackstaar | @mkeith I will order some of these and test them myself in my application. | |
| Jul 4, 2021 at 22:45 | comment | added | Hackstaar | @jsotola this is good to know. This implies no physical compression or tension on the element. | |
| Jul 4, 2021 at 22:44 | comment | added | Hackstaar | @mkeith I am not making a product to be protected by fuses. I am MANUFACTURING A SMART FUSE. The fuse itself is the end product. Of course, the fuse will be 'smart', implying that more than just the physical fuse element will be in this package. | |

| Jul 4, 2021 at 19:31 | comment | added | user57037 | Take a look at these, also: littelfuse.com/~/media/electronics/datasheets/fuses/… | |
| Jul 4, 2021 at 19:29 | comment | added | Passerby | Have you disassembled one? And have you look at the mini low profile mini and micro blade fuses for a smaller size you don't need to modify? Are you sure these 12~48V DC fuses will work at 240V AC without a datasheet to back it up? | |

| Jul 4, 2021 at 19:23 | comment | added | Kyle B | There are a zillion different fuse options out there. Its not true you that there isnt a suitable one for your purpose. You just havent found it yet. Check places that stock those options like MOUSER or DIGIKEY | |
| Jul 4, 2021 at 19:21 | comment | added | user57037 | I doubt very much anyone can answer your question with authority. Therefore you will have to try your modifications, then test the resulting fuse to make sure it meets your requirement. A word of caution: you may have a hard time convincing UL or similar agencies that your product is safe, if it relies on the fuse operating properly. And, to put it candidly, I think you are nuts to follow this course of action. There HAS to be another way. | |

| Jul 4, 2021 at 19:19 | comment | added | Finbarr | The element will blow at its thinnest point because the current causes the highest amount of heating there. The plastic enclosure offers insulation and a means to handle the whole assembly without damaging the element. | |
| Jul 4, 2021 at 19:19 | comment | added | Antonio51 | Fuses are concerned with "I2t energy" -> lead to Delta Temperature rise ... some usefull datas ... littelfuse.com/~/media/electronics/product_catalogs/… page 7 | |
