Product details

Drive selection memo

The Siemens 6SL3210-1KE21-7UB0 is a SINAMICS G120C variable-frequency drive rated for 7.5 kW output on a 380–480 V 3AC supply, with a 150% overload capability for 3 seconds. That overload headroom means it can handle short-duration peak loads — a conveyor start or a pump breakaway torque — without tripping or needing a larger frame. The drive integrates Safe Torque Off (STO) as standard, eliminating the need for a separate safety relay in many guarding circuits.

I/O and fieldbus

The I/O complement is 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed control, run/stop, and fault feedback without an expansion module. Fieldbus is USS/MODBUS RTU onboard; for PROFINET or EtherNet/IP you would add a communication board in the slot. The IP20 / UL Open Type enclosure means it mounts inside a panel, not on the machine frame — plan for a clean, filtered air environment.

Frequently asked questions

How do I get current pricing and availability for 6SL3210-1KE21-7UB0?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time — the part is sourced to order through independent distribution.

What is the closest alternative to 6SL3210-1KE21-7UB0 in the SINAMICS G120C family?

The SINAMICS G120C family includes other power ratings (e.g., 5.5 kW or 11 kW) in the same FSB frame size, but no pin-compatible drop-in replacement exists without re-rating the motor and supply. Verify the required power and overload profile before selecting an alternate order code.

What compliance documentation does Siemens provide for 6SL3210-1KE21-7UB0?

Siemens typically supplies a CE declaration of conformity, UL listing (UL Open Type), and RoHS/REACH compliance declarations for the SINAMICS G120C series. Request the specific documents from the distributor at quote time.
