Main function : The function of a rheostat is to adjust the circuit current between the maximum current at minimum resistance value, and the minimum current at rated resistance.

Electrical Characteristics : Two rheostats with the same power rating doesn’t mean they have the same maximum load current capacity.

For all FVR, FVRB and DSR-WB, please tell the followings :
i) maximum Resistance and minimum Current
ii) minimum Resistance and maximum Current
iii) Voltage at the minimum and maximum resistance

There are more Note and Tips for application limitation and parameters determination at the application page.
