GFHEV1-K series is a professional high-speed DC fuse designed for 250V direct current circuits. Covering 200A to 450A current specifications, it adopts fast-acting fusing characteristics, specially made for short-circuit and overcurrent protection of DC power systems.
This 250V DC high-speed fuse owns excellent arc extinguishing performance and rapid fault current breaking ability. It can respond within milliseconds when short circuit occurs, effectively protecting DC loads, semiconductor components and vehicle electrical modules from damage.
Compact structure, low heat generation and stable continuous current capability make GFHEV1-K fuse ideal for automotive DC systems, industrial DC power units and mobile energy equipment. Strict quality standards ensure long-term safe operation in complex DC working environments.
Fast acting DC fuse link is rapid response DC protective component, sensitive to sudden short-circuit current. Instant fusing, avoid DC circuit equipment burnout, widely used in DC power supply and DC equipment.
