The Siemens 6SL3210-1KE18-8UF1 is a SINAMICS G120C compact inverter rated 4 kW (5 hp) at 8.8 A for low overload, for a 3-phase 380 … 480 V supply, with PROFINET, EtherNet/IP communication.
Per the Siemens data sheet the drive is unfiltered, has an efficiency of 0.97 and efficiency class IE2 to IEC 61800-9-2, and a power loss of 119.0 W.
G120C drives are commissioned with an optional BOP-2 or IOP-2 operator panel or with Startdrive in TIA Portal, and integrate directly into SIMATIC S7-1200 and S7-1500 networks.

Compatibility and replacement
This G120C has PROFINET, EtherNet/IP on board; other G120C versions exist for USS/Modbus RTU and PROFIBUS, so check the fieldbus on the old drive. Operator panels BOP-2 (6SL3255-0AA00-4CA1) and IOP-2 (6SL3255-0AA00-4JA2) fit the G120C and are ordered separately.
Before you replace it
- Compare the full order number 6SL3210-1KE18-8UF1 with the rating plate of the old drive; the letters after the power code identify supply, filter and fieldbus version.
- Save or write down the parameters of the old drive if it still powers up; an operator panel can copy them.
- Check ventilation and cabinet temperature: drives derate or trip when the cabinet is too hot.
Frequently asked questions
LO or HO: which rating applies?
Low overload (4 kW, 8.8 A) suits pumps and fans; high overload (3 kW, 7.3 A) suits conveyors and machines with heavy starting torque.
Is an operator panel included?
No. Add a BOP-2 or IOP-2, or commission it with Startdrive in TIA Portal.
Which fieldbus does it have?
Per the Siemens data sheet: PROFINET, EtherNet/IP.
