 Fuses
UL class T fuses for branch circuit protection are listed below. Fast acting class T or
faster fuses are recommended in the USA.
Check from the fuse time-current curve that the operating time of the fuse is below
0.5 seconds for units of frame sizes R2 to R4 and 0.1 seconds for units of frame sizes
R5 and R6. The operating time depends on the supply network impedance and the
cross-sectional area and length of the supply cable. The short-circuit current can be
calculated as shown in
Frame sizes R5 and R6 (page 111).
Note 1: See also Thermal overload and short-circuit protection (page 44).
Note 2: In multi-cable installations, install only one fuse per phase (not one fuse per conductor).
Note 3: Larger fuses 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.
