Anybody got ideas about how the time/current curves on currently available fuses interact with some of the currently [Linked Image] available circuit breakers. (SqD,Siemens,Cutler/Hammer, etc)
Only asking below 600V, and up to only about 1000A.
It seems selectivity is normally not taken into consideration by designers, or the info just isn't available to them. Deadshort a 20, you'll blow a 100 ahead first. Short a 100, you'll blow an 800 first. [Linked Image]
