Description
Choosing the right fuse for a photovoltaic (PV) system is critical to the safe, reliable and long-term operation of this renewable energy source. The International Electrotechnical Commission (IEC) clarifies that the protection of photovoltaic systems differs from that of standard electrical installations. In IEC 60269-6, specified by the International Electrotechnical Commission, the specific characteristics that photovoltaic fuses need to meet are specifically defined to protect PV systems. CHIFENG's CFPV series string and branch photovoltaic fuses are specially designed to meet this standard.
CHIFENG have developed a cost-efficient, safe and long-life fuses for renewable energy system. As one of the CHIFENG's photovoltaic s, the CFPV1451 PV fuse is specifically designed for PV system with high rated voltage, and can open circuit safely under typical low fault current conditions produced by PV arrays.
