The SUNTREE SRF-30 DC FUSE LINK 10x38 1100V is a Direct Current (DC) fuse designed to protect electrical equipment and circuits from overcurrent in high-voltage DC systems. This fuse has a cylindrical shape with dimensions of 10x38 mm and is rated for voltages up to 1100V DC, making it suitable for use in solar power systems, energy storage systems, and other high-voltage DC applications. The fuse will blow and disconnect the circuit when current exceeds its rating to prevent potential damage to equipment and systems.
