Siemens 6SL3210-1KE14-3AF2 – SINAMICS G120C Inverter (1.5 kW, PROFINET, Integrated STO)

Technical Description

The Siemens 6SL3210-1KE14-3AF2 is a frequency converter (inverter) from the SINAMICS G120C series, designed for automation and motor control applications in industrial environments that require high efficiency, compact design, and integrated safety features.

With a rated power of 1.5 kW and an overload capacity of 150% for 3 seconds, the G120C ensures reliable performance even under demanding load conditions. It operates on a three-phase 380–480 V AC supply (+10/-20%) with a frequency range of 47–63 Hz.

The inverter features an integrated EMC Class A filter, compliant with industrial standards, and provides a protection class of IP20 / UL Open Type. It also includes a built-in PROFINET-PN fieldbus interface, allowing fast, secure, and seamless communication with Siemens control systems.

An integrated Safe Torque Off (STO) safety function enables secure motor shutdown without disconnecting the entire system’s power supply.

The I/O interface includes 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output, while auxiliary power is supplied via external 24 V.

Its compact FSAA format (173×73×178 mm – H×W×D) makes it ideal for installations with limited space while ensuring efficient heat dissipation and easy integration.
