Description

5H30L dc fuse link is gR full‑range fast‑acting EV dc fuse link for new‑energy vehicle on‑board battery, vehicle wiring system and inverter comprehensive over‑current & short‑circuit protection. This series covers rated current 150A‑300A at 450V / 500V DC with 20kA DC breaking capacity. It adopts high‑temperature‑resistant ceramic tube,99.99% pure‑silver variable‑cross‑section melt and high‑purity quartz‑sand arc‑extinguishing medium. Silver‑plated contact surfaces reduce temperature rise and power consumption. The unit withstands thermal shock,mechanical vibration shock,current impulse and chemical load. Custom time‑current performance characteristics are negotiable for special‑project demands.
