Suntree DC MCCB 250HPV 2Pole 1000v

SM8-250HPV series photovoltaic special DC molded case circuit breaker is suitable for DC grid circuit with rated voltage up to DC1200V and rated current of 250A. DC circuit breaker has overload long delay protection, short circuit instantaneous protection function , used to distribute electric energy and protect circuit and the power supply equipment is protected from the danger of overload, short circuit, etc.

The operating mechanism of the DC circuit breaker has the functions of quick closing and fast reading segmentation, compact structure, small size and convenient use.

1500V high-voltage components and corollary electrical equipment mean lower system cost and higher power generation efficiency, which will soon become the new favorite of the photovoltaic industry.

After the DC side input voltage is increased, more components can be connected per string, which can increase the string length by 50%. The DC cable used in the inverter is reduced, and the number of inverter and combiner boxes can be reduced accordingly. At the same time, the power density of the combiner box, inverter, transformer and other energy equipment is increased, the volume is reduced, and the workload in transportation and maintenance is also reduced, which is beneficial to the reduction of the cost of the photovoltaic system.

From a system point of view, higher input and output voltage levels can reduce AC/DC side line looses and transformer low-voltage side expected to be increased by 1.5-2%
