Schedule of limitations.
1) The fuse must be so mounted that creepage and clearance distances aren’t impaired in any
way.
2) When used in intrinsically safe apparatus it will be necessary to determine a surface
temperature classification for the fuse.
3) Max surface temp rise at 170% rated current ≤750mA=40C, 1A=45C, 3A=63C and
5A=114C.
