What does the 'U' suffix mean at the end of the ATS48 Soft Starters' part numbers?

Hvordan kan vi hjælpe dig i dag?

To order in the US with English only literature, the part number was changed for a short period of time to include the U suffix.
There is no difference in products ordered with U and without U suffix. Customers will get the same product.
The suffix U is no longer used to order this part number.
