Quick question, are there a set of standards out there for low voltage fuses? Is it ANSI, NEMA, IEEE, UL? Or is it just like some sort of understood agreement between companies? Links would be greatly appreciated , even if I have to buy them.
I am doing a arc flash hazard analysis and I have found something very interesting. There is a 500kVA transformer feeding into a 1600A fuse, then into a 208V lighting panel. The arcing current is 7140A, if this is then looked on up on the ANSI Time Current Curves, the burn through time is about...
Im looking into the differences between a bussmann RK1 and littlefuse RK1, ect. The curves are slightly different, that can be seen with just a glance, what I need to know is if that difference is anything substantial. The equations themselves are trade secrets, so all I have to go on is the...
I know there is a slight difference between the curves, but I need to know if that difference is signifigant. I know that medium voltage fuses do have signifigant differences and more thought goes into the selection. A similar claim has been made about RK1 and RK5 fuses and it is my task to...
Hello, I am currently working on a project and need some information on RK1 and RK5 fuse curves. The question has arisen if all bussmann, edison, littlefuse, and ferazz/shamute fuses are the same, ie interchangable.
