Siemens 6SL3300-1AE32-5AA0 SINAMICS S120 Braking Module

6SL3300-1AE32-5AA0 is the Siemens SINAMICS S120 Braking Module for a chassis unit GX. It connects to the 600 V DC link to dissipate excess energy; confirm the chassis hardware and DC-link rating before use.

6SL3300-1AE32-5AA0 is rated at 50 kW PDB, 250 kW P15 peak for 15 seconds, 200 kW P20 and 100 kW P40 in the official table. Match the duty cycle and braking-resistor data to the installed drive.

6SL3300-1AE32-5AA0 is associated with a SINAMICS S120 chassis unit GX. Do not substitute FX, HX or JX hardware until mechanical fit, DC-link voltage, busbar and control compatibility are verified.

6SL3300-1AE32-5AA0 uses R1/R2 M8 screw connections; the specified maximum connection cross-section is 50 mm² and the DC-link busbar current is 378 A. Verify cable sizing, torque and DC-link discharge before wiring.

6SL3300-1AE32-5AA0 has a 600 V DC input. The manual lists the X21 digital input as −3 to 30 V, with 15–30 V high and −3–5 V low, plus a 24 V DC output up to 500 mA; confirm the wiring.

Before installing or replacing 6SL3300-1AE32-5AA0, confirm the full article code, 600 V DC link, GX chassis fit, braking-resistor selection, 50 mm² cable limit, M8 terminals, isolation and discharge procedure, revision and saved drive configuration.

For 6SL3300-1AE32-5AA0, provide the exact nameplate, installed SINAMICS S120 chassis type, DC-link rating, braking-resistor data, connector and busbar photos, revision, quantity and replacement objective so compatibility can be checked independently.
