What 6SL5100-0EE25-5AD0 does in a SINAMICS S220 stack
The 6SL5100-0EE25-5AD0 is a Siemens SINAMICS S220 line reactor sized for a 55 kW Smart Line Module in booksize D construction, fed from a 380-480 V 3 AC mains (cite:). Line reactors sit upstream of the line-side converter module to tame the diode-rectifier commutation notch, limit line-side harmonic current, and protect the DC bus capacitors from inrush — without one, the SLM does not meet its published EMC and short-circuit withstand ratings. Because it is part of the Line reactors for Smart Line Modules family (cite:), it pairs one-to-one with the matching 55 kW SLM in the S220 booksize D footprint — same cabinet width, same DC-bus link, same cooling path. The line reactor is specified by the drive manufacturer; substituting a generic three-phase reactor with similar inductance will pass energization but usually trips the SLM on line-side monitoring because the impedance is outside the validated band.
Ratings and what they tell the panel builder
The 55 kW / 380-480 V 3 AC rating (cite:) defines the upper edge of the SLM power class this reactor supports — pick the line reactor by the SLM's rated power, not by motor nameplate, because the line-side converter handles the full regen flow, not just the motor shaft power. Catalog identifiers Group Code R220 and Product Group X0HX (cite:, cite:) are the internal Siemens classification slots used to order the matching air-filter, fan, and connector accessories for the booksize D booksize cabinet — quoting against these codes during a BOM pull avoids the common error of mixing S120 and S220 accessories, which share the booksize form factor but are not always pin-for-pin compatible.
Lifecycle status and compliance paperwork
Lifecycle stage is recorded as current and the product status is Active (cite:, cite:), so this is a part the factory is still producing and the SLM 55 kW platform it serves remains a supported configuration in the SINAMICS S220 catalog. Product class A (cite:) marks it as a standard stocked item that can be returned within the published return window — relevant for panel builders who routinely over-pull spares against a long-running frame contract.
Ordering and BOM positioning
Orderable in single-piece quantity (cite:, cite:); a line reactor is typically a one-per-drive line item on the BOM rather than a volume component, so the per-cabinet count rarely exceeds one or two unless the line has paralleled SLMs. For sourcing on a live S220 cabinet build or a maintenance spare, this part is specified into the BOM by its Group Code R220 / Product Group X0HX designation (cite:, cite:) — quoting against those slots alongside the SLM order code keeps the panel-builder accessory list coherent. Pricing and current availability for 6SL5100-0EE25-5AD0 are confirmed at quote time against the requested quantity.
