(1) The value "6 x P" is the result of an empirical relation which is estimated to represent most DC magnetic loads up to the highest limit of P = 50 W (6 x P = 300 ms). It is accepted
that loads having drawn energy above 50 W are made up of weaker loads in parallel. As a consequence, the 300 ms value must form the highest limit whatever the value of the
power drawn.

Key:

U (I) = applied voltage (current) Ic = making and breaking current expressed in DC or in AC like the 10

Ur = recovery voltage r.m.s. value of the symmetrical components

L/R = test circuit time constant T0.95 = time required to reach 95 % of the current in steady-state conditions,

Ue (Ie) = rated operational voltage (current) expressed in milliseconds
