Derating Characteristics for High-Efficiency Motors
TeSys H motor starters are designed for motors with a starting current (Is) that is eight times the nominal current (Ie), according to IEC 60947-4-2. For these motors, Is/Ie = 8.
The following tables list the maximum nominal current for motors where Is/Ie is greater than or equal to 8. If necessary, limit the maximum nominal current of these motors.
