Description

The Siemens 6ES5 988-3NB41 is a specialized fan replacement kit designed for high-capacity SIMATIC S5 power supply units. This thermal management component is essential for maintaining forced-air cooling across power electronics, preventing thermal throttling, and protecting sensitive components from heat-related degradation. It is engineered to support specific power supply models, including the 6ES5 955-3LC4X, 6ES5 955-3LF4X, 6ES5 955-3NC4X, and 6ES5 955-3NF4X series.

Features

Optimized for SIMATIC S5 rack enclosures with precise mechanical alignment.
High-velocity axial fan design to maximize static pressure and airflow throughput.
Vibration-resistant electrical connector for reliable power distribution.
Designed for continuous 24/7 operation in demanding industrial environments.
Constructed to withstand high ambient particulate loads common in heavy industry.

Applications

This fan kit is widely utilized in critical infrastructure applications, including power generation plants, petroleum refineries, and heavy mining operations. It serves as a vital maintenance component for extending the operational lifespan of legacy SIMATIC S5 automation backplanes by ensuring consistent heat dissipation within enclosed control panels.

Installation Guidelines

Ensure the power supply unit is fully de-energized before attempting to remove or install the fan kit.
Verify that the mounting surface is clean and free of debris to ensure an airtight seal between the fan housing and the power supply chassis.
Align the mechanical housing carefully with the existing chassis mounting points to prevent vibration during operation.
Ensure the electrical connector is fully seated and locked into the power distribution rail.
After installation, perform a brief test run to confirm the fan is spinning freely and that there are no obstructions to the airflow path.

FAQ

Is this fan kit compatible with all SIMATIC S5 power supplies?

No, this kit is specifically designed for the 6ES5 955-3LC4X, 6ES5 955-3LF4X, 6ES5 955-3NC4X, and 6ES5 955-3NF4X series. Please verify your power supply model number before installation.

Does the fan require external wiring?

No, the unit utilizes a plug-in connector that draws power directly from the internal power supply distribution rail, eliminating the need for external cabling.
