The Siemens Braking Resistor, part number 6SE6400-4BD21-2DA0, is a robust and reliable component designed for use with inverter drives in a variety of industrial applications. This braking resistor is engineered to safely dissipate energy generated during the deceleration of electric motors, thereby providing an effective means of braking and enhancing the overall control of motor speed. With a rated voltage of 480 V and a protection class of IP20, this component is suitable for a wide range of environments, ensuring consistent performance in diverse operating conditions. The braking resistor boasts a compact design, with dimensions of 175 x 515 x 270 mm, making it an ideal choice for systems where space is at a premium. The unit's electrical resistance is rated at 27 Ohms, and it can handle a maximum consumed active power of 24 kW, with a rated value of 1.2 kW. This allows for efficient energy absorption during high-power braking scenarios. The braking resistor is also equipped with a normally closed contact temperature switch, ensuring additional safety by monitoring the temperature and disconnecting the circuit if it exceeds the maximum threshold. Installation and maintenance are straightforward, thanks to the M6 screw studs for power and protective conductor connections, which also facilitate secure and reliable electrical connections. The braking resistor is designed to be compatible with a range of Siemens inverter drives, making it a versatile addition to your motor control setup. Overall, the Siemens 6SE6400-4BD21-2DA0 Braking Resistor is a high-quality component that offers dependable performance for controlling motor deceleration in industrial applications. Its durable construction and thoughtful design ensure it can meet the demands of rigorous industrial use.
