Note 1: See also Implementing thermal overload and short-circuit protection on page 62 . For UL recognized
fuses, see Fuses (UL) on page 110 .
Note 2: In multicable installations, install only one fuse per phase (not one fuse per conductor).
Note 3: Larger fuses than the recommended ones must not be used.
Note 4: Fuses from other manufacturers can be used if they meet the ratings and the melting curve of the
fuse does not exceed the melting curve of the fuse mentioned in the table.
