Atom Power Introduces First Ever Digital Circuit Breaker

May 21, 2019
New technology certified for widespread commercial use, bringing power distribution to the digital age for the first time.

Atom Power, inventor of the world’s first and only digital circuit breaker, today announced its technology is listed by Underwriters Laboratories (UL), the governing standard for consumer safety. This is the first time in the history of commercial power distribution that a digital solid-state circuit breaker has been listed by UL.   

Circuit breaker technology hasn’t fundamentally changed in more than 140 years. In that time, everything else has — from telegraphs and carriages to smartphones and electric vehicles.

Despite massive innovation in renewables, batteries and vehicles, the analog infrastructure hits a series of bottlenecks when these power sources meet at a single point, like a physical structure, according to Atom Power.

“Today, power is plentiful — renewable costs are falling, many structures have generators and batteries store more energy,” says Ryan Kennedy, CEO, Atom Power. “However, we’re missing a link that connects each source and manages the energy flow between it all. We need a new digital platform to dynamically and intelligently respond to this new era of power.”

Atom Power’s digital circuit breaker uses solid-state semiconductors and software to manage the flow of power and consolidates the functionality of many disaggregated commercial power components into one device. For the first time, every power source is fed into one point to control the energy flow and manage a building’s needs instantaneously.

To achieve UL489 and UL1557 — the standard listings for circuit breakers and power semiconductors — Atom Power had to meet an unprecedented series of construction and endurance requirements.

“We’ve never seen such a leap in power innovation as the advent of digital circuit breakers,” says Denis Kouroussis, co-founder and CTO of Atom Power. “As the first team to successfully build this technology, we were subjected to more testing than any traditional breaker. We not only passed each rigorous evaluation but surpassed expectations.”

Atom Power’s innovation captured industry attention, receiving investments from three of the four largest circuit breaker manufacturers — Siemens, ABB and Eaton.

“Siemens is proud to be on the forefront of energy innovation, and we’re committed to building partnerships with companies on the leading edge of electrification, automation and digitization,” says John DeBoer, director of eMobility and New Energy Business, Siemens. “Atom Power’s achievement of UL represents a great step toward the future of solid-state electrical protection. We’re thrilled to support them as their technology is applied to critical problems facing the power industry across generation, distribution and consumption in the digital age.”

Atom Power’s intelligent product suite includes a circuit breaker (Atom Switch), distribution panel (Atom Panel) and software (Atom OS) that forms the fastest power distribution system ever, enabling circuit interruption capabilities up to 100,000 A and reducing electrical explosion hazards to almost nothing, according to the company.
