SIEMENS 6SL3000-0BE23-6DA1 – Line Reactor for Harmonic Mitigation | SINAMICS S120 Platform
Engineering Background: The 6SL3000-0BE23-6DA1 is a Siemens SINAMICS S120 series line reactor (commutating choke) engineered to reduce harmonic distortion on the AC supply side of variable-speed drive systems. It is a passive inductive component inserted between the mains supply and the Active Line Module (ALM) or Basic Line Module (BLM) of the SINAMICS S120 booksize/chassis drive family. By limiting the rate of current rise (di/dt) during rectifier commutation, it protects upstream equipment, reduces THDi, and extends drive service life.
Product Positioning: Designed for procurement engineers specifying harmonic-compliance solutions in industrial automation, machine tool, and process-control applications. The 6SL3000-0BE23-6DA1 is the OEM-recommended line reactor for SINAMICS S120 drive configurations operating at 380–480 V AC, 36 A rated current. It is a direct Siemens factory part, fully compatible with TIA Portal commissioning workflows and CE/UL-certified installations.

System Architecture & Signal Flow
In a standard SINAMICS S120 drive line-up, the 6SL3000-0BE23-6DA1 is installed on the AC supply side, upstream of the Line Module. The signal/power flow is:
Mains Supply (3-phase, 380–480 V AC) → Main Contactor / Circuit Breaker → 6SL3000-0BE23-6DA1 Line Reactor → SINAMICS S120 Active/Basic Line Module → DC Bus → Motor Modules → Servo / Induction Motors
The reactor’s inductance creates a controlled impedance that smooths the rectifier current waveform, reducing harmonic injection back into the supply network and protecting both the drive and upstream distribution equipment.

Technical FAQ
Q: Is the 6SL3000-0BE23-6DA1 mandatory for SINAMICS S120 operation?
A: Not mandatory for basic operation, but strongly recommended by Siemens for all installations where supply impedance is low (<1%) or where harmonic standards (IEEE 519, EN 61000-3-12) must be met. It is required when using a Basic Line Module without an Active Front End.
Q: Can this reactor be used with other Siemens drive families (e.g., G120, S150)?
A: The 6SL3000-0BE23-6DA1 is dimensioned for the S120 36 A input stage. While physically compatible with other 3-phase 380–480 V systems, always verify inductance and current rating against the target drive’s input specification before substitution.
Q: What is the difference between a line reactor and a line filter (EMC filter)?
A: A line reactor (this product) is an inductive choke that reduces harmonic current distortion. An EMC/RFI filter additionally attenuates high-frequency conducted emissions. For full EMC compliance, both components may be required depending on the installation category.
Q: Do you provide a test report or certificate of conformity?
A: Yes. Siemens Declaration of Conformity and, upon request, a Konmask pre-shipment inspection report are available for every order.
Q: What is the lead time for stock and non-stock units?
A: In-stock units ship within 2–3 business days. Non-stock orders are subject to Siemens factory lead time (typically 4–8 weeks). Contact us for current availability.
