6SL3210-1KE18-8UF1
Product Overview
The Siemens SINAMICS G120C (6SL3210-1KE18-8UF1) is a compact and powerful 3-phase variable frequency drive (VFD) engineered for efficient and reliable motor control in industrial automation systems. Designed to operate on a 380–480 V AC 3-phase input, this model provides 4.0 kW (5 HP) in Low Overload mode and 3.0 kW (4 HP) in High Overload mode. As the unfiltered version, it is intended for use with an external EMC filter, offering flexibility for installations with specific noise-suppression requirements. It includes integrated Safe Torque Off (STO) safety functionality and an embedded PROFINET interface for modern industrial communication.
