What this module does on a SINAMICS S220 line-up
The 6SL5130-6UE25-5AC0 is a Smart Line Module in booksize format from the SINAMICS S220 family — a regenerative line-side supply that converts a 380-480 V 3 AC input into a 495-720 V DC bus that the motor-side inverters on the same booksize rack draw from, with internal air cooling as the only cooling path. Input current is 98 A, output power 55 kW, in a booksize C type footprint rated IP20. Because the line module regenerates rather than rectifies-only, the DC bus can push braking energy back to the supply on overhauling loads — important on vertical axes and high-inertia spindles where the alternative (a Basic Line Module with a brake chopper and external resistor) bleeds that energy as heat. The FW V2.4 SP1 HF10 baseline tied to this order code is the firmware level required for the S220 topology to behave as built.
Sizing the bus against the motor inverters
The 495-720 V DC output range defines the working window the downstream motor modules must be specified for — a motor module matched to a 600 V DC class is the natural pairing here. At 55 kW continuous, the line module sets the cabinet-level power ceiling: every inverter drawing from this bus must be load-summated under that figure, with the 98 A input current setting the upstream feeder and breaker rating. IP20 and internal air cooling only — the cooling path is the cabinet's own airflow, so the booksize C type clearance to adjacent devices and the cabinet's fan/filter arrangement drive the thermal margin more than the line module itself. This is a panel-build detail, not a chassis-mount unit; leave the documented clearances as specified.
