SCiBreak is hiring!

2020 is a big year for SCiBreak. We have started our first major customer project, providing grid protection for the Swedish Transport Administration, and we will also develop medium voltage DC switchgear as part of an upcoming EU research project. With our growing commitments ahead, our team needs to be expanded. We are currently looking …

SCiBreak wins order from Trafikverket

SCiBreak has been selected by Trafikverket (the Swedish Transport Administration) to develop and supply equipment for the Swedish rail network. Swedish railways are seeing increasing passenger streams, resulting in a need for more traffic. The power supply system needs to be upgraded, but this often leads to excessive short-circuit currents in case of faults, which …

LimBreak-Rail: New EUREKA-project together with Arcteq Oy on ultra-fast fault detection in railway applications

A bidirectional, ultra-fast DC-breaker, such as the breaker technology offered by SCiBreak, can with great benefits be used also in AC-systems. Especially in 16.7 Hz railway applications, the ability to dramatically reduce the total fault clearance time brings a unique and valuable tool to the grid owners. The requirements on and possibilities enabled by a …

About Us

SCiBreak is a Swedish company founded in 2014 to commercialize new technology for interrupting electric current. Our technology allows for interruption of high AC or DC currents with high returning voltage within a few milliseconds. Conventional AC breakers need several tens of milliseconds to break and existing DC breakers for high voltage are generally very costly. The parts cost of breakers based on the concept is considerably lower than that of competing solutions.

Our roots are in many ways at KTH Royal Institute of Technology in Stockholm where many of us have worked and studied.

SCiBreak is collaborating with InnoEnergy and Svenska Kraftnät.
