What is a solid-state breaker?

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.

What is a smart solid-state circuit breaker?

Smart solid-state circuit breakers enable the digitalization of power distribution to meet the growing demands for renewable energy. Watch the webinar to explore Infineon’s solutions for protection, measurement, programmability, communication, and actuation. Smart circuit breakers combine multiple functions into one single device.

What is the difference between a mechanical and solid-state circuit breaker?

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.

Is ABB a solid-state circuit breaker?

...ABB has invented a revolutionary solid-state circuit breaker concept that meets the highest demands of renewable energy solutions and industrial energy storage systems?

How fast can a solid state circuit breaker detect a short circuit?

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.

Why are solid-state circuit breaker variants gaining a bigger market share?

With advancements in the wide-bandgap semiconductor technology, solid-state circuit breaker variants are taking on a bigger market share. Wide-bandgap semiconductor switches have lower on-state losses and higher efficiency during normal operation compared to silicon-based semiconductors.
