Drive specs at a glance
The Siemens 6SL3210-1KE18-8UC0 is a SINAMICS G120C compact drive rated for 4.0 kW output power with a 150% overload capability for 3 seconds — enough to handle short-duration load spikes on pumps, fans, or small conveyors without oversizing the drive frame. It runs on a 380-480 VAC three-phase supply, 47-63 Hz, unfiltered, so it fits standard European and North American line voltages without an external line reactor for basic installations. The I/O interface gives you 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for a basic speed/start-stop control loop with a feedback sensor. Safe Torque Off is integrated, meeting SIL 3 / PL e for safety circuits that need to remove drive torque without a separate safety contactor. Fieldbus is CANopen onboard, so it drops into a CAN-based line architecture without an option card. IP20 / UL Open Type means it is meant for a clean, dry cabinet — not for washdown or outdoor mounting.
Lifecycle and sourcing reality
This drive carries a mature lifecycle stage — Siemens continues to manufacture it, but it is not a newly introduced model; the platform is established and widely deployed.
