A DC Molded Case Circuit Breaker (DC MCCB for short) is a protective electrical device designed specifically for DC circuits (such as photovoltaic systems, energy storage power stations, and electric vehicle charging facilities). Its operating characteristics are developed around core pain points of DC circuits, including “no natural zero-crossing point, difficult arc extinguishing, and special load characteristics”.
