Tests with 1.000 A/m magnetic field
During tests with a field of 1.000 A/m the primary current of variac NX1-260-16 during the 3s testtime goes to
approx. 39A. The motorvariac can withstand this load for this short time. The figure below shows the load
diagram. Therefore the variac NX1-260-16 can withstand during approx. 45s a current of 39A. Normally the fuses
do not break during the 3s test time.
