The Siemens 6SL3210-1KE11-8AB1 is a SINAMICS G120C variable-frequency drive sized for a 0.55 kW motor on 380-480 V three-phase supply. The 150% overload for 3 seconds handles short-duration peak loads like a conveyor start or a pump breakaway torque — that's the rating that governs real use, not the continuous kW figure. Integrated filter class A means it meets conducted emission limits for most industrial environments without an external EMC filter, saving DIN-rail space. The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — covers a basic speed/start-stop application without an expansion module. Safe-Torque-Off is integrated on the standard unit, so you can wire an emergency-stop safety circuit directly without a separate safety relay, provided the rest of the loop meets SIL 3 / PL e. Fieldbus is USS/MODBUS RTU on the standard port; no option card needed for those protocols.
Panel integration
The 73 mm width leaves room alongside a line reactor or braking resistor. The integrated filter class A is a built-in EMC filter, so no external filter is needed for CE-marked installations in industrial networks. For residential or light-commercial environments (class B), an external output filter may be required — check the local installation standard. The filter adds leakage current; ensure the PE ground is low-impedance and the RCD type is selective (type B or time-delayed) to avoid nuisance trips.
