Abbs type circuit breaker closing energy storage

What is ABB – solid-state 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.

Are solid-state circuit breakers a drop-in replacement for traditional electromechanical devices?

Solid-state circuit breakers are not a drop-in replacement of the traditional electromechanical devices. Their ultrafast interruption is a key enabler for new DC power distribution models that can improve energy efficiency and ease integration of distributed energy resources.

Why is a solid-state circuit breaker important?

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.

Are solid-state circuit breakers a viable solution?

A viable solution to such protection needs is given by solid-state circuit breakers (SSCBs), exploiting the latest development of power semiconductor technology, such as low-losses IGCTs and WBG FET devices.

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.

How many moving parts does A R-Mag circuit breaker have?

Using a flux-shifting device with integral permanent magnets, the R-MAG mechanism has only one moving part. With simple open and close coils, an electronic controller and capacitors for energy storage, the R-MAG circuit breaker mechanism is capable of 10,000 operations.
