What is the replacement for the High HP ATS01N softstarters?


20 July 2022

Part number for the replacement of the ATS01N High HP Soft Starters.

Product line:
ATS01, Altistart 01, High HP

All models

The launch of the ATS22 in 2011 caused the High HP units to become redundant.


The ATS01 High HP units were replaced with the ATS22 units.  These are functional replacements only.  The ATS01 had no overload protection, an internal power supply and simple dial adjustments.  The ATS22 will require external 120V or 230V power.  There are no dials to adjust, but the unit will need to be programmed.  See the ATS22 User Manual, document BBV51330 to review the wiring, dimensions and programming.  See the attached file.
