01
Product Identification
6SL3210-1SE21-8AA0 is a Siemens SINAMICS S120 PM340 Power Module for three-phase 380 to 480 V supplies. The AA0 suffix identifies the version with an integrated line filter.
This FSC module is rated at 7.5 kW, with a separate 5.5 kW high-overload type rating for loads sized by the heavier current profile.

Functions
- Provides the blocksize AC power stage for a SINAMICS S120 drive axis.
- Operates from a three-phase 380 to 480 V line supply under control of a compatible SINAMICS Control Unit.
- Includes an integrated line filter in the AA0 configuration.
- Supports a connected external braking resistor through the PM340 braking circuit.
- Supplies 18 A rated output current with 26.4 A peak capability for the documented load cycle.
04
Applications
- 7.5 kW standard induction-motor drive duties matched to the rated-current profile.
- 5.5 kW applications sized by the high-overload base current.
- Modular SINAMICS S120 machines requiring a compact blocksize power stage.
- Control cabinets that preserve the specified line reactor, filtering, cooling and braking arrangement.
05
Lifecycle
- Keep the complete 6SL3210-1SE21-8AA0 article number because the suffix identifies the filtered AA0 version.
- Before replacement, record the Control Unit, firmware, motor data, parameter set and braking-resistor connection.
- Match the FSC mechanical format, 7.5 kW rating and documented current profile.
- Verify current product availability and any proposed migration against the installed SINAMICS architecture before ordering.
