Motor Overload Setting Calculator
Use Motor Overload Setting to the overload current setting calculation. The loaded example shows the arithmetic with practical electrical units.
Enter values for overload current setting
Use one consistent electrical operating case for all fields.
How Motor Overload Setting works
The numerical relationship is setting = nameplate current × factor. Motor Overload Setting uses Nameplate current, Setting factor to report Overload current setting. Use Horsepower Kilowatt Calculator.
With the loaded values, overload current setting evaluates to 27.60 A. Retain the initial result as the comparison baseline.
Inputs for Motor Overload Setting
Nameplate current and Setting factor belong to Motor Overload Setting. Keep source units with nameplate current.
Replace every example value with data from one documented operating condition.

Reading the Motor Overload Setting result
This output represents Motor Overload Setting.
A computed value still needs comparison with standard equipment ratings and operating limits.
Measurement and units
Motor nameplate data, duty, enclosure, starting method, load profile, and thermal limits govern final selection. Check prefixes on nameplate current.
Matching units and measurement locations prevent false differences.
Limits of this calculation
Follow motor, controller, and code instructions. Compare this result with Motor Starting kVA Calculator when starting demand is also needed.
The displayed formula isolates the stated electrical quantity. Unentered effects remain outside Motor Overload Setting.
A useful Motor Overload Setting comparison
Record overload current setting before testing a different nameplate current value.
Document the alternate nameplate current source.
Motor Overload Setting record notes
Record source and operating details for nameplate current.
Retain raw overload current setting beside its selected rating. For motor slip, use Motor Slip Calculator.
