The solid-state breaker concept replaces the traditional moving parts of an electromechanical circuit breaker with semiconductors and advanced software algorithms that control the power and can interrupt extreme currents faster than ever before.

Solid-state technology guarantees an extremely fast interruption and clears a fault in a few microseconds. In comparison, a mechanical circuit breaker with the same frame size takes a few milliseconds. ABB’s solid-state circuit breaker can detect and respond to a short circuit fault 100 times faster than a mechanical circuit breaker.

Energy storage systems and their corresponding electrical grid services are strongly affected by the downtime in case of an internal fault. Rapid disconnection of the faulted zone can prevent a shut-down of the system. Because there is no energy released during current interruption, the chance of a dangerous arc flash occurring is reduced to almost zero.

Energy efficiency is a crucial aspect for all electrical installations, including those operating on islanded grids such as vessels with an onboard DC grid. Compared to other semiconductor technologies, ABB’s solid-state circuit breaker guarantees 70% less power losses during the conduction phase.

This technological breakthrough can enhance the performance and reliability of renewable energy solutions, industrial energy storage solutions and edge grids.
