ATS48 with 'U' suffix
Customer has ATS48 part number with a 'U' at the end of it
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.
(i.e. ATS48D17YU is the same Soft Starter as ATS48D17Y).
