AbolishedCircuit-breakers for overcurrent protection for household and similar installation—Part 3: Circuit-breakers for d.c. operation
家用及类似场所用过电流保护断路器 第3部分：用于直流的断路器
Application Summary AI generated
This standard specifies technical requirements and test methods for circuit-breakers designed to protect direct current (DC) circuits in household and similar installations. It is applied to DC-operated miniature circuit-breakers used in residential, commercial, and light industrial electrical systems, such as those in photovoltaic solar panels, battery storage systems, or DC distribution networks. The standard ensures these devices safely interrupt overcurrents and short-circuits in DC applications, where arc extinction is more challenging than in AC systems.
