Data record `std.ieee-1584.structure.fuse-clearing`

Verified 2026-10-24 Confidence: Medium

Clause 6.9.2 of IEEE 1584-2018 gives the rule for reading a fuse time-current curve for the arc duration, distinguishing curves that give total clearing time from curves that give only average melting time and deferring to the manufacturer above the current-limiting threshold; Annex H adds a simplified incident energy model for two fuse classes at the lowest anchor voltage and one electrode configuration, with Table H.9 supplying its constants.
