6SE6400-4BE21-3DA0

In the realm of industrial applications, the Siemens 6SE6400-4BE21-3DA0 serves as a crucial braking resistor tailored for integration with MICROMASTER 4 inverters. This device is engineered to absorb braking energy effectively during the deceleration phase of motor control, enhancing operational efficiency. It operates within a voltage range of 500 to 600 volts AC, ensuring compatibility with various power systems.

The component is characterized by a rated resistance of 39 OHMS, which optimizes the absorption of energy generated during braking. With peak power capabilities reaching up to 26 kilowatts, it demonstrates substantial performance under demanding conditions, while maintaining continuous power handling at 1.3 kilowatts for sustained operation. The design adopts a stand-alone mounting approach, simplifying installation, and is cooled through natural convection, alleviating the need for additional cooling systems.

Regarding environmental considerations, the 6SE6400-4BE21-3DA0 carries an IP20 enclosure rating, indicating that it is protected from foreign objects larger than 12.5mm but is not waterproof. This unit complies with RoHS directives, aligning it with current environmental safety standards. It can function efficiently within an operating temperature range from -10 to 40 degrees Celsius, making it suitable for typical industrial environments. Additionally, this braking resistor can maintain functionality in humidity levels ranging from 5 to 95%, provided that condensation does not occur. The 6SE6400-4BE21-3DA0 is an essential component for systems requiring reliable energy absorption during braking.
