I have obtained a surplus fuse, new old stock.

Buss JKS 400

Bussman Limitron
Quick-Acting
Current-Limiting
FUSE
JKS 400

Class J Fuse

Interrupting Rating
200,000 amp. rms sym.
600v or less A.C.


I was wondering if it would be suitable to act as a mid-pack fuse on my 128 VDC LiIon Leaf Module pack?

I found the following documentation, but it may be for a newer version of the fuse:
http://www.cooperindustries.com/content/dam/public/bussmann/Electrical/Resources/product-datasheets-b/Bus_Ele_DS_1027_JKS_70-600A.pdf

If I'm reading the graph right tt looks like the fuse would take 10 seconds at 1000 amps to melt?

I already have a 400 amp fuse up front with the motor controller. (it's a Littelfuse L25S-400 )


People who know what "class J" and "quick-acting" vs "very fast-acting" care to comment?

Jay
