    1 General 1 General The SK 1x5E series is based on the tried and tested NORD platform. The devices are characterised by their compact design and their optimum operational characteristics, and have uniform parametrisation. Due to dual phase control, not only a pure motor start, but also a soft start is possible. The phase control process was selected so that the resulting harmonic torques are kept as low as possible.
