What are the losses of iCT+ contactors?

Published date: 05 September 2018

iCT+ losses consist of constant and variable lossses. 
Constant losses are produced by the coil and you can find the inrush and seal consumption in product datasheet. For example 1.1VA steady consmption and 11VA inrush consumption for

Variable losses depends on the current flow via main pole. At rated current 20A, the power losses are 0.9W. These losses reflects P=R*I^2 calculation, so dependence is quadratic. Therefore if the current is half, the losses are 1/4. 
Or for example if current is 15A, the losses will be (15/20)^2*0.9 =0.51W
