30 Operation principle and hardware description
100 kA input cubicle (option +F274)
￭
The 100 kA input cubicle (option +F274) increases the short-circuit withstand rating
of the drive. The cubicle contains extra fuses. The 100 kA cubicle is installed adjacent
to the standard 65 kA incoming cubicle or input cubicle at the factory. The input power
cables enter the 100 kA input cubicle. All other customer cables enter the auxiliary
control cubicle or other supply unit cubicles. ABB does not install optional door devices
(for example, meters) on the door of the 100 kA cubicle at the factory. No UL version
(option +C129) is available.
