SINAMICS G120 | Siemens | 6SL3 244-0BB12-1BA1 6SL3244-0BB12-1BA1 SINAMICS G120 CONTROL UNIT

Product Description: 6SL3244-0BB12-1BA1

The 6SL3244-0BB12-1BA1 is a PM240-2 power module from the SINAMICS G120 family, rated at 55 kW motor output. It converts three-phase 380–480 V AC into a regulated DC link and drives the motor stage in modular G120 systems. This variant includes an integrated C1-class EMC filter, ensuring compliance with electromagnetic-compatibility standards without external components. Housed in a compact Frame Size F enclosure with internal fan cooling, it pairs with G120 control units (CU) to deliver high-performance drive solutions.
