1) Observe the notes in chapter 4.1.1 .
2) In order to increase energy efficiency, it is recommended to on‐
ly reduce the magnetizing current to 10 % after a cycle break
time of 2 s. In doing so, there is an anticipated reduction in no-
load losses of approx. 60 % at a no-load speed of 4000 rpm.
3) Tolerance ± 5%
4) Rated current limited by connection plug (power)
