Atom Power unveils 2nd-generation digital circuit breaker, incorporating SiC power modules

Atom Power of Charlotte, NC, USA, which invented what is claimed to be the first commercial digital solid-state circuit breaker, has unveiled its Generation 2 Atom Switch, which is now UL Listed to UL 489I — the standard for solid-state circuit breakers. In May, the Generation 1 Atom Switch was the first of its kind Listed to UL 489I.

The next generation of Atom Power’s technology contains the firm’s own proprietary silicon carbide (SiC) power modules, doubling the performance compared with the Generation 1 Atom Switch.

Atom Power is said to be the first company to use wide-bandgap (WBG) semiconductors in commercially available solid-state circuit breakers, and the only firm to manufacture SiC modules specifically for use in circuit protection. The models SWXFT100CPM and SWXFT50CPM SiC power modules are UL Recognized to UL 1557.

Innovations of the Generation 2 Atom Switch include: increased interrupting rating; additional firmware capability (including new internal self-diagnostic and enhanced maintenance functions); and significantly reduced manufacturing time (10-times faster to assemble than Generation 1).

“With the first-generation Atom Switch, we introduced the first ever circuit breaker on the market that completely controls the flow of power via software and solid-state semiconductors,” says co-founder & chief technology officer Denis Kouroussis. “Now, by incorporating semiconductor power modules that we designed and manufactured ourselves, we have taken our technology to the next level,” he adds. “With enhanced performance capabilities and faster assembly times, our Generation 2 circuit breaker is more accessible than ever and furthers our mission of revolutionizing power management.”

“The vision is to completely transform power distribution to meet our modern energy needs, and to reach a future where energy is fast, safe and intelligently controlled for the first time,” says CEO Ryan Kennedy. “The Generation 2 circuit breaker marks a new milestone in fulfilling that vision and making intelligent power more accessible and attainable to more people.”
