Hi,

depend the model of breaker. If only have the Ir setting is only realize a simple operation:

Nominal current breaker * Ir. THis is, Ir=0.8 (80%) and the breaker nominal current 400A. The adjust is 400 * 0.8 = 320A.

thank you, is the same thing if we have a breaker with 80% rated  if we set Ir= 0,8 the breker nominal curent 400A the adjuste will be 400*0,8 + = 320 a or it is another thing thank you
