The rated DC short-circuit capacity is limited to 10,000 A .
Here are the to obtain the standard:
IEC 60898-2 defines international requirements for circuit-breakers operating on both alternating current (AC) and direct current (DC) up to 125 A, specifically addressing the challenges of DC arc extinguishing in household installations. This standard covers essential parameters for DC applications, including specific time constants ( iec 60898-2 pdf
Do not risk using a pirated or outdated copy. Purchase the official standard from the IEC Webstore or your national body. The cost is small compared to the peace of mind and legal compliance it provides.
Standard AC circuit-breakers (compliant with IEC 60898-1) are not designed to interrupt DC current. DC arcs are continuous and more difficult to extinguish because the voltage does not pass through a natural zero point twice per cycle. A breaker designed only for AC may fail catastrophically if used on a DC circuit, leading to fire or equipment damage. The rated DC short-circuit capacity is limited to 10,000 A
Once you have your legitimate copy, here is a quick roadmap for the busy engineer:
Elias pulled up his tablet, swiping quickly to the he kept bookmarked. While Part 1 of the standard covers AC-only breakers, Part 2 is the "holy grail" for mixed systems. It outlines the rigorous requirements for circuit breakers designed to handle both AC and DC current, specifically for domestic and similar installations where voltages don't exceed 440V.

The International Electrotechnical Commission (IEC) publishes various standards for electrical equipment, including circuit-breakers. One such standard is IEC 60898-2, which outlines the general rules for circuit-breakers used in equipment. In this article, we'll provide an overview of IEC 60898-2 and its significance in the electrical industry.
