Siemens 6SL3100-0BE25-5AB0 SINAMICS S120 Active Interface Module 55kW 380-480V Drive Module

The Siemens 6SL3100-0BE25-5AB0 is a SINAMICS S120 Active Interface Module sized for the 55 kW Active Line Module, accepting a 3 AC 380-480 V, 50/60 Hz supply at up to 88 A input current. It supplies the line-side filtering and decoupling reactance the Active Line Module needs for regenerative, sinusoidal-current operation in book-size drive configurations.

Selection Notes

This 55 kW-rated Active Interface Module pairs with its matching Active Line Module frame — choose it over the smaller 36 kW variant once line-side current exceeds 58 A, since its 88 A rating and larger 200 mm x 380 mm x 270 mm enclosure carry the additional continuous load. The higher 0.083 m³/s cooling air throughput reflects the larger 0.380 kW loss figure, so cabinet ventilation should scale accordingly.

Applications

The 50 mm² conductor cross-section and larger 200 mm x 380 mm x 270 mm footprint accommodate the higher 88 A input current without derating. Its 66 dB sound pressure level runs slightly above the 36 kW variant's, a relevant figure when sizing enclosure noise budgets for panels near operator stations.
