Current Limiting Fuse Application Information
Current Limiting Fuse Application Information
(OP)
Hello,
I'm looking for information on applying current limiting fuses, particularly for arc flash hazards. The IEEE Red Book only contains a very brief discussion of CLFs. Does anyone have any links to resources?
Thank You

RE: Current Limiting Fuse Application Information
When considering CLFs for arc-flash protection, the biggest issue is making sure there is enough short-circuit current available to get the fuse into its current-limiting range. If the fuse takes longer than 1/2 cycle to operate, it isn't current-limiting.
