What this card is for
The 6SL3356-3AG33-3AA0 is a replacement Interface and Protection Device (IPD) card for a SINAMICS S120 liquid-cooled Motor Module rated 315 kW at 500-690 VAC three-phase, 50/60 Hz, 330 A. It's the control and monitoring board that sits between the drive control unit and the power stage — not the power module itself, but the logic board that manages gate drive, current sensing, and fault handling for that specific liquid-cooled chassis.
RoHS compliance dates from July 1, 2017.
