ABB NBRA-653 Brake Chopper

The ABB NBRA-653 Brake Chopper is an electronic device used in variable speed drives to dissipate the kinetic energy of an electric motor during deceleration. When a motor is being driven by a variable speed drive, the energy generated by the motor can be fed back into the drive when the motor is decelerating. This can cause a voltage spike that can damage the drive's components. The brake chopper is used to dissipate this energy in the form of heat, protecting the drive and ensuring safe operation.

The ABB NBRA-653 Brake Chopper is specifically designed for use with ABB drives, and is compatible with a range of different drive models. It has a maximum braking power of 3200 watts, and can be used with motors up to 690 volts.

Overall, the ABB NBRA-653 Brake Chopper is an important component in variable speed drive systems, helping to ensure safe and reliable operation of electric motors in a wide range of industrial and commercial applications.
