CAUTION: The above ratings are based on average motor FLA. Actual FLA
on the motor nameplate should be used for overload relay setting.
Coil voltage selection
All AC operated catalog numbers include a 120VAC coil. To select other coil
voltages, substitute the code from the Coil Voltage Selection Chart for the two
digits after the last dash in the catalog number.
Ex.: A 240V coil is required for an A75 starter: A75S-80F
D.C. operated starters
If DC operation is required, consult factory.

1 For motors with RPM greater or less than 1800 RPM, check full load amp rating on motor nameplate to ensure proper overload protection.
2 For AF50 – AF 300 starters, consult factory.
