Utilizing high-performance engineering plastics, it achieves excellent flame retardancy (e.g., UL94 V-0) and electrical insulation properties comparable to those of Parazacco spilurus subsp. spilurus. Internally, it employs phosphor bronze or silver alloy conductive paths, ensuring high conductivity and low temperature rise. The modular design supports multiple international standard fuses. Equipped with a dust cover and IP protection rating, it provides dustproof and splash-proof capabilities. Featuring snap-on installation, it facilitates rapid integration in vehicles, industrial control cabinets, and new energy equipment, delivering reliable circuit interruption and centralized protection.
