What the ratings mean for your panel
The 6SL3210-1KE21-7AC1 is a SINAMICS G120C spare-part drive rated for 7.5 kW continuous output on a 380-480 VAC three-phase supply, with a 150% overload capability for 3 s — enough to handle a pump or conveyor start without oversizing the drive frame. The IP20 / UL Open Type enclosure means it is intended for installation inside a clean, dry control cabinet; it is not rated for washdown or outdoor exposure. Frame size FSB (196 x 100 x 203 mm) fits the standard DIN-rail footprint for this power class, so panel layout and gland-plate planning follow the G120C family dimensions.
Lifecycle and sourcing reality
No official successor order code is listed, so the 6SL3210-1KE21-7AC1 remains the current spare part for G120C drives at this power rating. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Integration notes
The drive integrates a Class A EMC filter, CANopen fieldbus, and Safe Torque Off (STO) as standard — no option cards needed for these functions. I/O complement: 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output. External 24 VDC supply required for the control logic. The 150% overload for 3 s is the short-term peak capability; continuous duty at 7.5 kW is the sizing basis for the motor and cabling.
