For interruptions of 0 to 100% and 100% to 0% the internal Variac is not involved, therefore the test
can be carried out up to 16 A. For interruption with UT =EUT Power 1 voltage not zero, the internal
variac limits the EUT power current. The maximum allowed current values are listed in the table on
the next page. Please be aware that different types of loads influence the maximum current.
