Drive selection memo — 0.55 kW, compact frame
The Siemens 6SL3210-1KE11-8AP1 is a SINAMICS G120C variable-frequency drive rated at 0.55 kW with a 150% overload capability for 3 seconds — enough headroom to start a small pump or fan under load without oversizing the drive. Input accepts 380-480 V three-phase, 47-63 Hz, with an integrated Class A EMC filter, so it meets conducted-emission limits for most industrial environments without an external filter. The IP20 / UL Open Type enclosure means it mounts inside a control cabinet, not on the machine frame. Safe Torque Off (STO) is integrated, eliminating the need for a separate safety relay in a Category 3 / PL d safety circuit.
