6SL3300-1AE32-5AA0 is a Siemens SINAMICS G130 braking module for the 380–480 V three-phase converter class. It transfers regenerated DC-link energy to the assigned external braking resistor when a controlled deceleration would otherwise raise the DC-link voltage.

The module is assigned to GX-size chassis applications and must be selected together with the documented power module and resistor. Its short-time ratings are duty-dependent, so a matching article number alone does not replace an energy and thermal calculation.

• Provides a controlled path for regenerative energy during dynamic braking events.
• Offers two documented response thresholds selected through the module DIP switch.
• Includes 24 V digital input and short-circuit-proof digital output circuitry for supervisory integration.
• Uses the manufacturer-defined module, power-module and resistor assignment rather than a generic resistance-only selection.

• High-inertia machinery requiring controlled rapid deceleration.
• SINAMICS G130 chassis drives with frequent stopping or overhauling loads.
• Retrofit of the same braking-module execution after the installed resistor and duty cycle have been verified.

• Record the complete power-module and braking-resistor article numbers before disassembly.
• Calculate regenerated energy, braking duration and repetition rate against the published load cycle.
• Isolate the converter, wait for the specified DC-link discharge time and prove absence of voltage before work.
• After replacement, verify threshold selection, resistor wiring, thermal protection and a controlled deceleration test.
