Description
ABB's HVDC circuit breaker is a pioneering hybrid DC breaker solution for medium and high-voltage DC grids. Combining fast mechanical switches with power electronics, it interrupts DC fault currents in less than 5 milliseconds - hundreds of times faster than traditional mechanical breakers. This breakthrough enables the development of multi-terminal HVDC grids and offshore wind collection systems.
