100 kA input cubicle (option +F274)
￭
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 beside 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. The factory installs no optional door devices (such as meters, etc.) on the
door of the 100 kA cubicle. No UL version (option +C129) is available.
