Product Introduction
Molded case DC circuit breaker is suitable for DC power grid circuits with rated voltage DC250V～DC1500V, rated current 10A～1250A, photovoltaic power generation system, inverter, photovoltaic combiner box, etc. It has the functions of overload long-time delay protection and short-circuit instantaneous protection. It is used to distribute electric energy and protect lines and power supply equipment from overload, short circuit and other faults.
Product Features
- The operating mechanism has quick closing and quick breaking functions2. The installation of dynamic and static contacts in the contact arc extinguishing system has the principle of parallel conductors. The H-type static contacts can be separated, which is conducive to rapid breaking when large currents are present. High-resistant Components made of arc material are conducive to fast arc quenching;3. Compact structure, small size4. Thermal magnetic, leakage, DC, intelligent unified dimensions5. Independent installation unit for accessories, users only need to open the accessory cover to install and replace accessories;6. Zero flashover or short flashover, safe and reliable operation
