SIEMENS 6SL3351-6GE41-0AB3 Active Line Power Module – SINAMICS S120 Series
When a SINAMICS S120 drive system loses its Active Line Module, the consequences are immediate and severe: production lines halt, servo axes lose coordinated control, and regenerative braking capability disappears entirely. Unplanned downtime in automotive stamping, paper mills, or CNC machining centers can cost thousands of dollars per hour. The SIEMENS 6SL3351-6GE41-0AB3 is the precision-engineered replacement that restores full drive functionality without compromise.
Within the SINAMICS S120 booksize cabinet kit family, the 6SL3351-6GE41-0AB3 occupies a critical position as a high-power Active Line Module designed for demanding regenerative drive applications. SINAMICS S120 is Siemens’ flagship multi-axis drive platform, deployed across tens of thousands of installations worldwide in industries ranging from automotive manufacturing to offshore energy. This specific module variant delivers clean sinusoidal current draw from the supply network while enabling energy recovery during braking cycles — a capability that defines modern energy-efficient drive architecture.
