Siemens 6SL3210-1KE18-8AB0

SINAMICS G120C | Compact Variable Frequency Drive | 4.0 kW | 9.0 A | 380–480 V AC | USS / Modbus RTU

Product Detailed Description

The Siemens 6SL3210-1KE18-8AB0 is a SINAMICS G120C compact frequency converter designed for speed control of three-phase AC motors in industrial automation systems. It has a rated power of 4.0 kW under low-overload operation and supports a three-phase input voltage of 380–480 V AC.The drive integrates a Class A EMC filter, USS and Modbus RTU communication, and Safe Torque Off (STO) functionality. Its built-in I/O includes six digital inputs, two digital outputs, one analog input, and one analog output, providing flexible integration with PLCs and machine control systems.With its compact FSA frame, IP20 protection, and integrated cooling fan, the G120C is suitable for installation in industrial control cabinets.

Important Application Note

The 4.0 kW rating applies to low-overload operation; the high-overload rating is 3.0 kW. Do not select the drive based on power alone. Check motor current, load profile, overload requirements, communication protocol, and STO wiring. Also distinguish the bare-unit weight of 1.70 kg from the 2.3 kg net weight shown in Siemens’ product listing, which may reflect a different packaging or catalog configuration.
