What it is and what it does
The Siemens 6SL3501-0BE22-0AA0 is an internal braking resistor for the SINAMICS G110M drive series, frame size FSB. It dissipates regenerative energy from the DC link when a motor decelerates, preventing overvoltage trips. Peak power is 200 W; continuous rating is 20 W at 175 ohm, which means it handles short, infrequent deceleration events rather than sustained braking duty. The IP20 enclosure suits it for inside a control cabinet — no washdown or outdoor exposure.
Integration notes
Dimensions are 34 x 11 x 84 mm (HxWxD) — it mounts directly onto the SINAMICS G110M FSB drive frame, not on a separate DIN rail. Ambient operating range is -10 °C to +55 °C, so derate if the cabinet internal temperature exceeds that. The 175 ohm resistance is fixed; verify it matches the drive's DC-link voltage class and the motor's regenerative energy profile before specifying.
