Siemens 6SL4113-0CA08-0AF0 SINAMICS G220 3AC 400V 1.1kW FSA IP20 Variable Frequency Drive

The Siemens 6SL4113-0CA08-0AF0 is a SINAMICS G220 variable frequency drive rated 1.1 kW (low overload) at 3AC 380–500 V, frame size FSA with IP20/UL Open Type protection. The unit ships with an integrated braking chopper, a 1.4" graphic display, and dual Ethernet interfaces — PROFINET and Modbus TCP — ready for plant-network integration without add-on modules.

Selection Notes

The 6SL4113-0CA08-0AF0 is the FSA entry point in the G220 range, and its 1.1 kW LO / 0.75 kW HO split matters directly for application selection: pumps and fans with quadratic load profiles that never exceed 110% sustained torque can use the full 1.1 kW LO rating, while compressors or conveyors demanding 200% peak torque must be sized to the 0.75 kW HO figure. The 5.9 A maximum output current gives defined headroom above the 3.9 A LO rated current for starting transients. The integrated braking chopper allows direct connection of an external braking resistor without an add-on module, relevant wherever regenerative braking is needed in the FSA footprint. Because this variant ships unfiltered, a separate line filter is required to reach EN 61800-3 Category C2/C1 conducted-emission limits; specifying an FSA-matched filter at order time avoids a retrofit.

Applications

FSA physical dimensions (250 × 73 × 209 mm) fit 73 mm-pitch control-cabinet slots. The 0…480 Hz vector-control output range covers standard 2-pole and 4-pole motors operating at elevated speeds, while the 0…550 Hz V/f ceiling accommodates high-speed spindle or textile-machine profiles. PROFINET and Modbus TCP on a single unit simplifies integration into either SIMATIC S7-based architectures or third-party Modbus supervisory systems without a fieldbus gateway. SIL 3 safety functions are available on-board, removing the need for an external safety relay in STO circuits up to SIL 3 / PLe.
