Description
The ABB DC Circuit Breaker is a high-performance protection device designed specifically for direct current (DC) applications such as solar power systems, battery storage, EV charging, and industrial DC networks. Unlike conventional AC breakers, ABB DC breakers are engineered to safely interrupt DC fault currents, ensuring reliable protection against overloads and short circuits.
Available in multiple series such as S200 M DC, S800 PV-M, Tmax XT, and Emax 2, these breakers cover a wide range of ratings from small residential solar systems to large utility-scale projects. With breaking capacities up to 1500 V DC and current ratings up to 6300 A, ABB DC breakers deliver outstanding performance, compact design, and long-term reliability.
Certified under IEC/EN standards, ABB breakers are globally trusted for their durability, polarity independence, and advanced arc-extinguishing technology. Whether for rooftop solar arrays, battery energy storage systems, or industrial DC applications, ABB ensures maximum safety and efficiency.
