Zhejiang Hongman Electric Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of ev fuse dc 2000v in China. We are committed to providing high quality customized products made in China with competitive price. Welcome to wholesale bulk cheap ev fuse dc 2000v from our factory.
Product Introduction
This Blade Ceramic Fuse is a 2000V high-voltage blade fuse developed for harsh DC operating conditions, also named EV Blade Fuse 2000V. Adopting high-purity alumina ceramic housing and high-purity quartz sand arc-extinguishing filler, it perfectly matches high-voltage DC systems including new energy passenger & commercial vehicles, large energy storage power stations and PV DC combiner boxes. It solves defects of traditional low-voltage fuses such as insufficient voltage resistance, easy cracking under high temperature and weak breaking capacity. It can operate stably at -55℃~125℃, cut off short-circuit & overcurrent fault within milliseconds, effectively avoid battery thermal runaway and high-voltage fire hazards, serving as the core safety protection component for 2000V DC platforms.
