| Third-party BLM equivalents | 530 A class | Consult Konmask for verified cross-reference |
Note: Always verify DC link voltage, DRIVE-CLiQ firmware version, and cabinet dimensions before substituting modules.
Why Choose the Original Model
- Exact firmware compatibility — native DRIVE-CLiQ handshake with S120 Control Units (CU320-2, CU310-2)
- Guaranteed DC bus matching — no derating calculations required
- Siemens warranty support — eligible for Siemens repair and exchange programs
- Proven field reliability — widely deployed in steel, paper, and heavy process industries
- Simplified commissioning — plug-and-play with STARTER / TIA Portal V16+
Typical Applications
- Heavy-duty multi-axis drive systems (steel mills, rolling lines)
- Large pump and compressor drives in oil & gas
- Paper machine section drives
- Mining conveyor and hoist systems
- Centralized DC bus architectures with multiple Motor Modules
- Crane and lifting equipment with regenerative braking
System Compatibility
The 6SL3330-1TE35-3AA3 is designed to operate within the SINAMICS S120 Booksize / Chassis platform and is compatible with:
- Control Units: CU320-2 DP, CU320-2 PN, CU310-2 DP/PN
- Motor Modules: All S120 Chassis Motor Modules sharing the same DC bus
- Line Filters: 6SL3000-0BE35-3AA0 (recommended EMC filter)
- Line Reactors: 6SL3000-0CE35-3AA0
- Braking Modules: 6SL3300-1AE32-5AA0 and equivalents
- Software: STARTER V5.4+, TIA Portal V15.1+, SINAMICS Startdrive
Selection Guide
Use the following criteria to confirm the 6SL3330-1TE35-3AA3 is the right module for your application:
- Step 1 — Calculate total motor load: Sum the rated currents of all Motor Modules on the shared DC bus. The BLM input current must exceed this total by ≥10%.
- Step 2 — Verify supply voltage: Confirm 3-phase 380–480 V AC supply with ≤±10% variation.
- Step 3 — Check cabinet space: Confirm chassis dimensions and cooling airflow clearance (min. 100 mm top/bottom).
- Step 4 — Confirm firmware: Match DRIVE-CLiQ firmware version with existing Control Unit to avoid compatibility errors.
- Step 5 — Assess regeneration needs: BLM is non-regenerative; if regenerative braking is required, consider the Active Line Module (ALM) series instead.

Replacement & Compatibility FAQ
Q: Can I replace 6SL3330-1TE35-3AA3 with a higher-rated BLM?
A: Yes, a higher-rated BLM (e.g., 6SL3330-1TE38-4AA3) is electrically compatible but requires verifying cabinet space and DC bus wiring ratings.
Q: Is this module interchangeable with the Active Line Module (ALM)?
A: No. The BLM is non-regenerative and uses a different control topology. ALM and BLM are not directly interchangeable without system redesign.
Q: What firmware version is required?
A: SINAMICS S120 firmware V4.7 SP9 or later is recommended. Always match the firmware version across all DRIVE-CLiQ components.
Q: Do you supply refurbished units?
A: Yes. Refurbished units are fully tested, clearly labeled, and carry a 90-day warranty. Contact us for pricing.
Q: Can this module be used outside the SINAMICS S120 platform?
A: No. The 6SL3330-1TE35-3AA3 is designed exclusively for the SINAMICS S120 Chassis system and is not compatible with other drive platforms.
