The Altistart 22 rating is limited to 3.5 IcL. IcL is the nominal current of the Altistart 22. If the application requires a
higher rated starting current (> 3.5 IcL), the soft starter must be oversized.
Do oversize selection as below.
Motor maximum starting current <= 3.5 ICL with
- Class 10 protection motor (Max. starting time of 16 seconds) than nominal size of starter as per nominal motor current (FLA)
- Class 20 protection motor (Max. starting time of 32 seconds) than oversize starter by one rating as compare to nominal motor current (FLA)
- Class 30 protection motor (Max. starting time of 48 seconds) than oversize starter by two ratings as compare to nominal motor current (FLA)
