The Next Generation in Circuit Breaker Technology
The grid of the future requires the circuit breaker of the future.
Atom Power revolutionized the circuit breaker by creating the world's first commercial UL-listed digital solid-state circuit breaker.
With a solid-state circuit breaker, on/off control is intrinsic to the device. Once metering and communications are added, you have the perfect mechanism to enable edge-of-the-grid distributed energy resource management.
Our solid-state circuit breaker, the Atom Switch, uses a semiconductor to interrupt current flow instead of a mechanical device. This means there are no moving parts involved when opening and closing a circuit. Other integral components include voltage and current sensors, power supply, control board, and communication supply.


Communication Supply
Control Board
Takes inputs from the current sensor and calculates when to operate the transistor. It can also be used for communication and outputting a user interface through a display or LEDs.
Current Sensors
Meters and calculates when to operate the breaker in an overload or fault condition, enabling us to program the solid-state circuit breaker to open at any current value based on a specified time - so a single design can cover a large range of current ratings.
Power Supply
The communication supply enables communication to other breakers and the control system.
Converts AC power from the circuit breaker panel bus into DC power for the control board.
Atom SiC Module
Our Atom Power designed and produced silicon carbide module provides unparalleled circuit protection in a simplified form factor.
Integral Air Gap Disconnecting Device
The integral air gap disconnecting device with integrated lockout/tagout features the set of mechanical contacts needed to provide galvanic isolation of the circuit.





Our patented solid-state circuit breaker technology can power buildings, homes, factories, and data centers. It can facilitate multiple energy sources, like solar and the grid. It creates a new standard for the electrified world that is safer, more efficient, more secure, and has the highest reliability.
Today, it charges electric vehicles.
