What is the difference between the ATS48 soft starter that has a part number that ends in Q versus one that ends in Y?
Issue:
Difference between the ATS48 soft starter that has a part number that ends in Q versus one that ends in Y.

Product Line:
Altistart ATS48

Environment:
All serial numbers

Cause:
Customer in US is looking for an ATS48M10Q.

Resolution:
The ATS 48 ``Q`` was made for sale every where except the US.  It has 2 CT`s and a max voltage of 400 vac. The ``Y`` series has 3 ct`s and a max voltage of 690 vac.
If replacing an ATS48Q with a Y, it is very important to determine the full load amp rating of the motor. The ATS48**Q can be connected to the motor ``inside`` the Delta. This greatly reduces the amperage on each phase of the soft starter, allowing a smaller unit than normal to be applied to a motor. This is not currently possible with the ATS48**Y soft starters.
See the attached manual pages 92 to 94 (pages 11 to 13 of the electronic document)
