The Siemens 6SL3371-7TE35-6AA0 is a spare part for the SINAMICS S120 drive system — specifically an IPD S120 Chassis-2 Active Line Module (ALM) rated at 400 V and 355 kW. This is the regenerative front-end that supplies the DC link and manages line harmonics; if the original unit in a multi-axis cabinet fails, this spare drops in to restore the common DC bus.
RoHS compliant since 14 December 2017. REACH candidate-list information is available per Article 33. The group code is R2SC and the product group is 4929 — these are Siemens internal cataloguing fields that help cross-reference the part in their ordering system.
