Features: 1. With high-quality diodes, the rectifier circuit only allows current to pass in one direction and blocks it when reversed to prevent reverse current from burning out the solar panels. 2. T2 red copper conductor, silver-plated surface, wear-resistant, corrosion-resistant, small resistance, and strong conductivity. 3. Lightweight and easy to use, simple to install, safe, and has a long service life. 4. The standardized universal solar fuse holder is compatible with photovoltaic cables with different insulation diameters. Designed for a variety of DC applications. 5. IP68 waterproof and dustproof standard, not afraid of rain, not afraid of dripping, can be used in various environments. 6. Rated current: 30A, rated voltage: DC1000V, temperature range: -40℃-+90℃, flame class: UL94-VO.
