Product Details：

Product Dimensions：

The Siemens 6SL3200-0ST07-0AA0 is a specialized maintenance component within the Sinamics S120 drive system family. Specifically, it is a Replacement Fan (spare part) designed for Chassis-format Power Units. Because high-performance frequency converters generate significant heat during operation, this fan is a critical internal component that ensures the power electronics remain within their safe operating temperature range.

Product Parameters

The technical specifications for the 6SL3200-0ST07-0AA0 are centered around its electrical requirements and mechanical fit for the Sinamics Chassis units.

Product Brand: Siemens
Product Family: Sinamics S120
Product Type: Spare Part / Replacement Fan
Input Voltage: Primarily operates on $230 \text{ VAC}$ (single-phase) or $400/480 \text{ VAC}$ depending on the internal power supply of the specific drive chassis it is installed in.
Frequency: Compatible with $50/60 \text{ Hz}$ electrical systems.
Net Weight: Approximately $2.5 \text{ kg}$ to $3.0 \text{ kg}$ (varies slightly by manufacturing batch).
Dimensions: Specifically sized to fit the internal mounting bracket of the S120 Chassis Power Units.
Life Expectancy: Designed for long-term industrial use, typically rated for tens of thousands of operating hours under standard conditions.

Product Advantages

OEM Precision: As an original equipment manufacturer (OEM) part, it provides a 1:1 match for the original fan, ensuring that airflow pressure and volume meet the exact thermal requirements of the drive.
Plug-and-Play Installation: The unit comes with the necessary connectors and housing frames, allowing for quick replacement during scheduled maintenance windows.
Enhanced Drive Longevity: By maintaining optimal cooling, this fan prevents premature aging of capacitors and IGBTs (Insulated Gate Bipolar Transistors) inside the drive.
Integrated Diagnostics: When connected to the Sinamics S120 system, the drive can often monitor the fan's operation and provide warnings if the fan stalls or fails, preventing unexpected system shutdowns.

Important Considerations and Precautions

High Voltage Hazard: Before attempting to replace the fan, ensure that the Sinamics S120 Power Unit is completely disconnected from the power supply. You must wait for the internal discharge time (usually 5 to 20 minutes) as indicated on the drive's warning label.
Orientation Matters: Ensure the fan is installed in the correct airflow direction. Installing the fan backward will cause heat to build up inside the chassis, leading to an overtemperature fault.
Regular Cleaning: While the fan is a replacement part, the air filters in the cabinet should be checked and cleaned regularly to prevent the fan from working against high static pressure, which can shorten its lifespan.
Firmware and Parameters: In some cases, after replacing a fan, it may be necessary to acknowledge a fault or reset a maintenance counter within the drive's software (STARTER or Startdrive).
ESD Protection: Handle the fan and its connectors with Electrostatic Discharge (ESD) precautions to avoid damaging the drive’s internal control circuits.

Product Applications

The 6SL3200-0ST07-0AA0 fan is used exclusively within the Sinamics S120 Chassis Power Units. These large-scale drives are found in heavy industrial applications where precise motor control and high power output are required.

Metals and Mining: Used in drives for rolling mills, conveyors, and hoist systems.
Oil and Gas: Found in large pumping stations and compressor drives.
Pulp and Paper: Cooling the drives that manage the continuous high-speed movement of paper machines.
Marine and Offshore: Cooling propulsion drives and large winch systems on ships.
Energy and Water: Applied in high-capacity water pumps and fans used in power plant cooling towers.
