For maximum rating at voltages between the maximum design value and 120V, the maximum make and break ratings
are to be obtained by dividing the volt-amperes rating by the application voltage. For voltages below 120V, the
maximum make current is to be the same as for 120V, and the maximum break current is to be obtained by dividing the
break volt-amperes by the application voltage, but these currents are not to exceed 2 A.
