Digital circuit breaker startup raises funds
Investors in the latest round include: Valor Equity Partners, ABB Ventures, Rockwell Automation and Atreides Management. It brings the total raised by Atom Power to $23 million which includes a $3 million Series A round of funding in 2017.
Atom Power was founded in 2014 by CEO Ray Kennedy and uses silicon-carbide components to develop its solid-state circuit breaker. The aim is to avoid the micro-arcing that is possible with electromechanical circuit breakers, which are a safety hazard in some circumstances.
The specification that the company is working to is to deliver 99.9 percent efficiency at full power load and withstand a 600 percent overload in case of a failure. They should switch off in microseconds rather than the milliseconds taken by electromechanical systems. The ability to use digital control could make such devices useful in industrial and electricity distribution applications and electrical vehicle charging.
First-generation products from Atom Power received Underwriters Laboratory approval in 2019. The company also offers electricity distribution panels based on its digital circuit breaker and software.
