Do you need to take into consideration the service factor of the motor when setting the trip range on the Solid State Motorlogic overload relay?

Product Line:

Environment:

Cause:
Product features

Resolution:
If the continuous - rated motor has a service factor of 1.0, then you would set the dial to 90% of the motor's full load current.
Otherwise, there is a built in service factor of 1.15 - 1.25. If the continuous - rated 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 others.
