Siemens 6SL3220-3YE34-0UF0 Variable Frequency Drive for SINAMICS G120X

The Siemens 6SL3220-3YE34-0UF0 (6SL3220-3YE34-0UF0) is an industrial variable frequency drive belonging to the Siemens SINAMICS G120X series. Designed specifically for pump, fan, and compressor applications in water, wastewater, building automation, and industrial infrastructure systems, this frequency inverter delivers reliable and energy-efficient speed control for three-phase asynchronous motors. It operates within a standard three-phase AC input voltage range of 380 V to 480 V and provides steady motor regulation to optimize process throughput and reduce mechanical wear on driven equipment. With a net weight of approximately 10 kg, the unit is engineered for straightforward cabinet installation and reliable integration into automated drive architectures. The drive features robust construction suited for demanding continuous-duty operational environments, delivering stable motor control, overcurrent protection, and thermal monitoring during standard industrial cycles. It serves as a direct replacement component for servicing existing machinery, commissioning new pump or ventilation panels, and minimizing downtime in mission-critical processing lines.
