ABB reinvents the circuit breaker

A technological breakthrough by ABB – solid-state circuit breaker – will enhance performance of renewable energy solutions, industrial battery storage solutions and so-called edge grids.



ABB has developed a revolutionary solid-state circuit breaker concept, which meets the highest demands of next-generation power applications as they enter the digital age. The ground-breaking low voltage circuit breaker concept will be revealed to the public for the first time at the Hannover Messe in Germany. The product will be available from 2020.

The ABB solid-state circuit breaker concept will make electrical distribution systems more reliable and efficient and will drive down maintenance costs while meeting the durability demands of next-generation electrical grids. The ABB solid-state circuit breaker will help customers to address the main challenges of future energy requirement with ABB innovation and quality, thanks to:

Unlimited protection to satisfy new emerging applications such as renewable.

Grid edge ready to lead the next generation of electrical grid

Simple and safe solution to fit the customers need, easy to integrate in any kind of system.
