‡ Typical Voltage Drop (Measured at rated current after temperature stabilizes)
‡‡ Alpha code to be marked on the top (white) side of the fuse body for all ratings.
It is recommended that fuses be mounted ceramic (white) side facing up.
Device designed to carry rated current for four hours minimum. An operating current of 80% or less of rated current is recommended, with further derating required at
elevated ambient temperatures.
