3.2 Device design
3.2.1 SK 150E-1-O-3D-T125
The SK 150E-1-0 (Mat. No. 275101500) is a soft starter without permanently integrated rectifier. However, it is
possible to install a rectifier by Getriebebau NORD. This can be utilized in case of retrofitting or at system
voltages of < 380 V. Spacer bolts are used for the assembly of the rectifiers. (Æ See also chapter 5.1 )
3.2.2 SK 150E-1-BSG2-3D-T125
The design with integrated fast acting brake rectifier has the designation SK 150E-1-BSG2 (Mat. No.
275101505). With this device design, a fast acting brake rectifier has been added to the basic function to
directly control a brake mounted to the motor. Consequently, the brake voltage supplied equals supply voltage
x 0.45. The jumper [L] can be used to affect a gradual switch off by shorting the integrated DC switch. (Æ See
also chapter 5.1 )
