5H30L dc fuse link<\/strong> is gR full\u2011range fast\u2011acting EV dc fuse link for new\u2011energy vehicle on\u2011board battery, vehicle wiring system and inverter comprehensive over\u2011current & short\u2011circuit protection. This series covers rated current 150A\u2011300A at 450V \/ 500V DC with 20kA DC breaking capacity. It adopts high\u2011temperature\u2011resistant ceramic tube,99.99% pure\u2011silver variable\u2011cross\u2011section melt and high\u2011purity quartz\u2011sand arc\u2011extinguishing medium. Silver\u2011plated contact surfaces reduce temperature rise and power consumption. The unit withstands thermal shock,mechanical vibration shock,current impulse and chemical load. Custom time\u2011current performance characteristics are negotiable for special\u2011project demands.<\/p>\n
