ABB NBRA-658C Braking Chopper

Product Overview
The ABB NBRA-658C is a general-purpose braking chopper designed for overvoltage protection and braking control in industrial automation systems. It is primarily used in conjunction with three-phase inverters operating at 400V or 500V, providing braking support for ABB ACS800, ACS550, and other drive series, as well as third-party drives. The module is installed in the DC link (DC+ and DC- terminals) to dissipate energy during rapid motor braking, preventing inverter damage caused by overvoltage. Its modular design and high power rating make it suitable for medium- to high-power industrial braking applications.
