What Are 1500VDC Photovoltaic Fuses Used For?

1500VDC photovoltaic fuses are mainly used to protect circuits and components in photovoltaic power generation systems to prevent short circuits, open circuits and other faults from damaging the system. ‌ When a short circuit fault occurs in the circuit, the fuse will instantly melt and disconnect the circuit, thereby playing a protective role.

Specifically, 1500VDC photovoltaic fuses are suitable for photovoltaic power generation systems with a rated voltage of 1500V DC, and the rated current ranges from 1A to 100A. This type of fuse is usually connected to photovoltaic panels and photovoltaic cells to provide short circuit and open circuit protection for variable current systems. Its rated breaking capacity is generally above 10KA, in line with IEC60269.6 standards.

In addition, the 1500VDC photovoltaic fuse also has a high-strength porcelain melting tube and a specially treated arc medium to ensure stable operation under high pressure and high temperature environments. Its structure includes a variable cross-section melt made of 99.99% pure silver sheets, encapsulated in high-purity quartz sand and special chemical materials to ensure good electrical contact and fast breaking capacity.
