What's inside Delta connection on ATS22 & ATS48?

Inside delta connections can be inserted in series in the motor windings (6 - wire). They are powered by a current which is less than the line current by a factor of √3, whichenables a starter with a lower rating to be used.
This option can be configured in the Advanced settings menu (dLt = On). The nominal current and limiting current settings as well as the current displayed during operation are on-line values and so do not have to be calculated by the use
