The “NH2XLPV 1500V DC 63A–400A” is a high-performance DC fuse designed for use in photovoltaic (solar) power systems. These fuses are built to operate at a high direct current voltage of up to 1500 volts and provide protection for circuits carrying currents between 63A and 400A. They play a crucial role in safeguarding solar installations by interrupting excessive fault currents and preventing damage to modules, wiring, and other components. With robust design and excellent thermal performance, these fuses are essential in meeting the safety and reliability demands of modern renewable energy systems.
