NEMA and Definite Purpose Contactors and Starters

9065 Solid State Overload relay

If the  motor has a service factor of 1.0, then you would set the dial to 90% of the motor's full load current.
The solid state overload has a built in service factor of 1.15 - 1.25. If the motor has a service factor of 1.15 - 1.25,
set the dial to the motor's full load current rating. All other service factor ratings will need to be calculated by the motor manufacturer.
