6SL3210-1KE21-7UF1
Product Overview
The Siemens SINAMICS G120C (6SL3210-1KE21-7UF1) is a compact and powerful 3-phase variable frequency drive (VFD) designed for industrial motor control and automation applications. It operates on a 380–480 V AC 3-phase input and delivers 7.5 kW (10 HP) in low-overload (LO) mode and 5.5 kW (7.5 HP) in high-overload (HO) mode.
This unfiltered version (UF) does not include an integrated EMC filter, making it ideal for systems with external EMC filtering. The G120C series combines robust performance, network communication via PROFINET, built-in Safe Torque Off (STO) functionality, and a compact IP20 housing, optimized for OEM, panel, and machine-level automation.
