Available Products
What are Solid-State Circuit Breakers?
Solid-State Circuit Breakers (SSCBs) are modern devices that protect electrical circuits from damage due to overcurrent, overload, and short circuits. Unlike traditional electromechanical breakers, SSCBs use semiconductor switches instead of mechanical parts, offering superior performance.
Key Advantages of SSCBs:
Faster Interruption
Operate hundreds of times faster (microseconds vs. milliseconds), interrupting current before it becomes hazardous.
Enhanced Durability
No mechanical wear and tear, allowing for unlimited connect/disconnect cycles without degradation.
No Arcing
Semiconductor switches connect and disconnect without producing arcs, eliminating the need for arc-suppression features.
Intelligent & Adjustable
Can be dynamically adjusted, connected to intelligent networks, and monitored remotely for precise control and versatility.
SSCBs are ideal for a wide range of applications, including residential, commercial, and industrial AC systems, as well as HV DC systems like electric vehicles.
SSCB Market Information & Trends
The solid-state circuit breaker market is on an upward trajectory, driven by the need for more advanced and reliable circuit protection. Key trends include:
Steady Market Growth
Expected to reach USD 552 TWh in total capacity by 2030 (CAGR of 37%), fueled by declining Li-ion battery costs and increasing solar infrastructure deployment.
DC Market Expansion
The DC market for SSCBs is expected to rise significantly, as they are highly suitable for applications in ships, urban subways, trams, and battery systems (e.g., data centers).
AC System Replacement
For AC systems, SSCBs' capability to withstand high voltage fluctuations makes them essential for traditional power systems, positioning them to replace conventional circuit breakers.
EV Charging Infrastructure
The demand for robust electric vehicle (EV) charging infrastructure is creating significant opportunities for market expansion in the coming years.
