The Siemens 6SL3366-2NG00-0AA0 is the power cabling set for installing a 50 kW Braking Module inside a SINAMICS S120 Basic Line Module of frame size GB. This is a drive-system accessory — it connects the braking chopper to the DC link, letting the module dump regenerative energy from a motor load (conveyor, hoist, centrifuge) into a braking resistor instead of tripping the drive on overvoltage.
What the group code and product group tell you
The Group Code R220 and Product Group 4926 are Siemens internal classification tags. R220 groups it under SINAMICS S120 cabling and accessories; 4926 is the broader industrial-drive components category. These codes matter when you're searching a Siemens legacy catalog or filtering a spares database — they confirm this is the correct harness family for the GB-frame Basic Line Module, not a generic power cable.
