What the 106 A rating means for a motor load
That figure is the full-load current it can handle continuously in a standard panel — enough for a 55 kW motor at 400 V three-phase, assuming a typical service factor. The control supply is 110–230 VDC; the operating frequency is 50/60 Hz.
Integration: panel fit and wiring
Mounts on DIN rail or with screws — the fastening method supports both screw and snap-on mounting. The main current circuit uses screw-type terminals; the stranded wire range is 2x (10–70 mm²) and solid wire 2x (0.25–2.5 mm²). For auxiliary contacts the AWG range is 2x (24–14). Minimum load is 20 %, meaning the soft starter needs at least that much motor current to regulate properly — don't use it on a motor that draws less than about 21 A. The maximum motor cable length is 300 m, which covers most industrial runs.
