The Siemens 6SL3356-3AG41-0AA0 is a spare-part Interface and Protection Daughterboard (IPD card) for the SINAMICS S120 liquid-cooled Motor Module rated at 1000 kW on a 500-690 V 3AC supply at 50/60 Hz, carrying 1025 A continuous output current. This is the control/power interface board that sits inside the Motor Module — not the module itself. If you are rebuilding a liquid-cooled S120 drive on a 690 V line and the IPD card failed, this is the exact replacement board.
The part is manufactured in compliance with the EU RoHS directive since 01-04-18. The REACH candidate-list substance is lead at >0.1% w/w, so the standard SCIP notification applies for EU market placement.
