The CF520 Series is our high-performance line of 5x20mm ceramic tube fuses. Unlike glass fuses, these ceramic bodies are filled with high-purity quartz sand to quench electrical arcs during faults, providing a high breaking capacity (HBC) of up to 1500A. Essential for power supplies, UPS systems, and industrial controllers.
