6SE6400-4BC18-0DA0

The 6SE6400-4BC18-0DA0 model from Siemens is a braking resistor utilized in applications where inverters operate without applied filtering. This component functions effectively within a voltage range of 200 to 240 volts and is capable of withstanding a maximum DC link voltage of 450 volts. With a resistance value of 10 Ohms, it is designed to assist in energy absorption during braking processes.

In terms of power, the continuous rating stands at 800 watts, while the peak power can reach as high as 16 kW, allowing it to handle significant loads brief periods. The IP20 protection rating indicates that it is best suited for indoor environments, protecting against solid objects larger than 12.5 mm but not against moisture.

Constructed from metal, the housing features a mesh design, ensuring ventilation and heat dissipation during operation. The dimensions of the device are 515 mm in length, 270 mm in width, and 175 mm in height, and it weighs approximately 7 kg, making it manageable for installation. Additionally, it requires wiring of AWG 10 size to ensure adequate electrical connections. This braking resistor plays a critical role in maintaining the efficiency and reliability of its related inverter systems.
