Siemens Sinamics G120C Inverter drive, 3-phase, 400VAC, 2.2kW, 6A Part number 6SL3210-1KE15-8AF2

Product Overview

The Siemens 6SL3210-1KE15-8AF2 is the Siemens SINAMICS G120C 2.2 kW 3-phase Inverter Drive, designed for variable-frequency motor control in industrial applications. It accepts 380…480 V AC three-phase supply and provides a compact, efficient, and flexible solution for controlling AC motors — suitable for pumps, fans, conveyors, compressors and general machine drives.

Key Features

• Output power: 2.2 kW (low-overload rating – 150% for 3 s)
• Input voltage: 3-phase 380…480 V AC (±10% / –20%), 47–63 Hz
• Compact design — width ~73 mm, height ~173–178 mm, depth ~160–178 mm, ideal for tight control cabinet installations
• Integrated EMC filter (Class A) for reduced electromagnetic interference
• Wide control capability: V/f control, sensorless vector control, variable-frequency output (0–550 Hz) for flexible motor speed/torque management
• Built-in I/O interface: multiple digital inputs and outputs, analog I/O — for direct integration with automation systems and sensors
• Support for fieldbus / network communication (e.g. PROFINET / EtherNet-IP) when used with appropriate option modules — enables easy integration into networked control systems
• Cooling via integrated fan — suitable for continuous industrial operation under nominal conditions
• IP20 / open-type enclosure — intended for installation inside control panels or electrical cabinets
