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 section Frame sizes R5 and R6 on
page 110.
Note 1: See also Planning the electrical installation: Thermal overload and short-circuit protection.
Note 2: In multicable 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.
