the iMX is never energized after the tripping of the unit.
The coil of the iMX is energized only a few time allowing the tripping.
That explains why we don't give any permanent values of current,just the inrush current value.
Regarding the consumption, it is the same as the old Multi9 range,you will find attached the required values.
Also,you can use the formula P=VI to calculate the consumption,as the voltage and the inrush current is mentioned in the attached catalog page.
