2 Phase DC MCCB

A DC MCCB (Direct Current Molded-Case Circuit Breaker) is essential in providing protection against electrical hazards in DC systems. Compared to traditional fuses, they offer reduced maintenance costs, increased safety, and higher breaking capacities. DC MCCBs come in two main types: thermal magnetic and electronic trip, and should be properly selected based on system requirements. By regularly inspecting and testing MCCBs, proper functioning and protection is ensured. DC MCCBs have a wide range of applications, including renewable energy systems and industrial machinery.
