Compressors with this marking are suitable for direct or partial winding start. The motor winding is
subdivided into two parts:
Until type code A044: Part winding 1 = 60% and part winding 2 = 40%. This winding division
reduces the start-up current needed for a part winding start to approx. 65% of that for a direct start.
From type code A047: Part winding 1 = 50% and part winding 2 = 50%. This winding division
reduces the start-up current needed for a part winding start to approx. 50% of that for a direct start.
