6SE6400-4BC21-2EA0

The Siemens 6SE6400-4BC21-2EA0 functions as a braking resistor tailored for MICROMASTER 4 inverter systems. Its primary role is to absorb energy generated during the braking phase, facilitating smooth deceleration for connected motors. Operable at a rated voltage between 200 and 240 volts AC, the resistor boasts a rated resistance of 6.8 ohms, enabling it to efficiently manage electrical load during braking conditions.

This component can handle peak power spikes up to 24 kW, while its continuous power handling is rated at 1.2 kW, ensuring reliable operation under typical conditions. The unit has an IP20 enclosure rating, providing a basic level of protection from solid objects but not against moisture or liquids.

For installation, the braking resistor features a stand-alone design with flexibility in mounting orientation, although vertical placement is recommended for optimal performance. Cooling is achieved through natural convection, allowing the resistor to function without the need for additional cooling mechanisms. Operating within a temperature range from -10 to 40 degrees Celsius, this unit is suitable for a variety of industrial environments. Additionally, it complies with RoHS standards, reflecting adherence to environmental regulations.
