2H38L fast\u2011dc\u2011fuse<\/strong> is gR full\u2011range fast\u2011acting automotive DC fuse for heavy\u2011duty new\u2011energy vehicle DC\u2011circuit protection. This series covers 200A\u2011500A rated current at 250V \/ 300V DC with 10kA 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 contacts reduce temperature rise and power consumption. It provides comprehensive protection for charger,power supply,on\u2011board battery and inverter. Custom time\u2011current characteristics can be negotiated for special\u2011project demands.<\/p>\n
