The 6SL3356-3AE37-5AA0 is a Siemens SINAMICS S120 replacement IPD card — the Interface and Power Distribution board — for a liquid-cooled Motor Module rated 400 kW at 380-480 V three-phase, 50/60 Hz, pulling 745 A. This is a spare part, not a standalone drive: it slots into the liquid-cooled Motor Module chassis in a SINAMICS S120 cabinet drive system, typically found on high-power conveyors, extruders, or marine drives where liquid cooling is specified. The IPD card handles the DC-link connection, internal power distribution, and communication to the Control Unit — if it fails, the whole Motor Module drops out. Swapping the card restores the module without replacing the entire power section.
RoHS compliant since 01-04-18. Group code R2SC and product group 4Q30 are Siemens internal classification codes used for catalog sorting and spare-parts cross-reference. They do not affect fit or function.
