ABB ACS800-U7 User Manual

Technical data
117
Supply cable:
• length = 170 m
• resistance/length = 0.112 ohm/km
• reactance/length = 0.0273 ohm/km.
The calculated short-circuit current 9.7 kA is higher than the minimum short-circuit current of the drive
gG fuse type OFAF3H500 (8280 A). -> The 500 V gG fuse (ABB Control OFAF3H500) can be used.
Notes concerning the fuse tables
Note 1: See also section Thermal overload and short-circuit protection on page 46. For UL recognized
fuses, see section NEMA data on page 123.
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.
