E-Gen75

Dial	Description	Adjustment.
N	The number of poles.	Do not adjust. All models should be set to 4P3D only.
Io	Base rating.	This should be set to the maximum allowable continuous current. Reduce Io first before adjusting Ir.
Ir	Long-Time Pickup Current. Long time-delayed trip timer activates if above this value multiplied by Io. This is the continuous current trip rating.	Adjust Ir for fine tuning only after reducing Io.
Isd	Short-Time Pickup Current. Short time-delayed trip timer activates if above this value multiplied by Ir. This is the short current spike rating.	Do not adjust. All models should be set to 1.5 only.
