Mains Cable Fuses - ABB ACS800-U4 Hardware Manual

Mains cable fuses

Fuses for short-circuit protection of the mains cable are listed below. The fuses also
protect the adjoining equipment of the drive in case of a short-circuit. Check that the
operating time of the fuse is below 0.5 seconds. The operating time depends on
the supply network impedance and the cross-sectional area, material and length of
the supply cable. See also Electrical installation planning:
short-circuit
Note 1: In multicable installations, install only one fuse per phase (not one fuse per conductor).
Note 2: Mains cable sizing is based on a correction factor of 0.71 (max. 9 cables laid on a cable ladder
side by side, ambient temperature 30 °C, EN 60204-1 and IEC 364-5-523). For other conditions, size
the cables according to local safety regulations, appropriate input voltage and the load current of the
drive. You can choose a thicker cable but the fuses must be rated according to the table (bigger fuses
must not be used).
Note 3: Fuses from other manufacturers can be used if they meet the ratings.
