6SL3210-1SE21-0AA0 is a SINAMICS S120 PM340 blocksize Power Module with an integrated line filter. It is rated at 4 kW, uses frame size FSB and operates from a three-phase 380 to 480 V supply.

The module provides 10.2 A rated output current and 9.1 A high-overload base current. It is one part of a modular SINAMICS drive and requires a compatible Control Unit, line-side design and motor connection.

• 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 10.2 A rated output current with 20.4 A peak capability for the documented load cycle.

• Use with a compatible SINAMICS S120 Control Unit and supported firmware for the installed machine.
• The documented line-reactor selection for 6SL3210-1SE21-0AA0 is 6SL3203-0CD21-4AA0.
• For the integrated-filter configuration, the Category C2 shielded motor-cable limit is 25 m.
• The external braking resistor must be greater than 160 ω and its cable must not exceed 15 m.
• Motor reactors, line protection and conductor sizes must be selected for the exact current and frame.

• Keep the complete 6SL3210-1SE21-0AA0 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 FSB mechanical format, 4 kW rating and documented current profile.
• Verify current product availability and any proposed migration against the installed SINAMICS architecture before ordering.
