The Siemens 6SL3210-1KE21-7UC1 is a SINAMICS G120C drive rated for 7.5 kW with a 150% overload capability for 3 seconds. It runs on 380-480 V three-phase AC and integrates CANopen fieldbus. Safe Torque Off is built in, and the IP20 / UL Open Type enclosure suits panel-mount installations. The FSB frame size (196 x 100 x 203 mm) determines the DIN rail footprint and gland plate layout for panel integration.
What the ratings mean for fit
The 7.5 kW rating with 150% overload for 3 seconds means this drive handles short-duration peak torque — useful for starting conveyors or pumps under load without oversizing. The 380-480 VAC input range covers standard European and North American industrial supplies. CANopen fieldbus is integrated, so no option card is needed for that protocol. The 6 DI, 2 DQ, 1 AI, 1 AQ I/O interface covers basic machine control without an extra I/O module. Safe Torque Off (STO) is integrated, which simplifies safety circuit wiring — no external safety relay needed for the stop function. The IP20 rating means it's for clean, dry indoor panels only; no washdown or outdoor duty.
