The Siemens 6SL3366-4DU00-0AA0 is a spare-part cable for contactor monitoring on SINAMICS S120 Basic Line Modules (BLM), Smart Line Modules (SLM), and Motor Modules (MOMO). It is a made-to-order line item (Product class C), not a stocked shelf part — each unit is manufactured per order, which means it cannot be returned for credit once produced.
This is not an obsolete or NRND part — it remains in Siemens' current catalog for new builds and replacement orders. Because it is a C-class product, lead times are tied to Siemens' production schedule rather than off-the-shelf availability.
RoHS compliant since 01-07-19. REACH candidate-list information is available on request. Group code R2SC, product group 4929.
