SINAMICS S220 booksize, 45 kW class
The Siemens 6SL5120-1UE28-5AD0 is a Single Motor Module from the SINAMICS S220 line in booksize format, fed from a 495–720 V DC bus and delivering 0–480 V three-phase output at 85 A for a 45 kW motor — the booksize D frame ships with internal air cooling only and an IP20 chassis rating, and it requires firmware V5.2 SP3 HF10 or later to commission. Input current at the DC bus is 106 A, which sets the line-side fuse and DC-link cabling requirement on the cabinet build. Booksize D with internal air cooling means the module mounts on the standard SINAMICS booksize backplane inside a sealed cabinet; the heat is dumped into the cabinet air path, so cabinet sizing, fan redundancy, and the ducting above and below the module carry the thermal design rather than a remote heatsink or cold plate.
Headline ratings and what they drive on the BOM
Rated output 85 A at 0–480 V 3AC and a 45 kW nameplate place this module squarely in the mid-power SINAMICS S220 bracket — it covers machine tools, packaging lines, and converting machinery where a single servo axis or coordinated group needs that power ceiling without stepping up to a larger chassis. The 106 A DC input current is the figure the cabinet builder uses to size the line module feeder, the DC bus bar, and the upstream fuse or breaker on the rectified input. IP20 is an inside-the-cabinet rating only — the module expects a sealed enclosure to keep the cooling path and the backplane clear of contamination, so a plant-floor cabinet with appropriate ingress protection is mandatory for any washdown, food-grade, or outdoor installation.
Compliance, firmware, and commercial identity
The module is RoHS-compliant since 02-09-19 and carries a REACH Art. 33 disclosure for lead (CAS 7439-92-1) above the 0.1% w/w threshold, which is the standard Siemens booksize exemption for high-performance power electronics and travels on the declaration of conformity. Export classification is AL:N / ECCN 3A999A — outside the dual-use EAR99 lane, so most commercial shipments do not require an export licence, but transactional screening is still done at the order desk.
Lifecycle and sourcing posture
Lifecycle stage reads as Active and current — Siemens still lists the order code in the booksize motor module line, so the panel builder and the MRO buyer can plan long-term on this part rather than scrambling for a last-time-buy slot. No LTB date, PCN, or successor cross-reference is on the ledger, which means the current part is the part to specify.
