<\/p>\n

H14FE high-speed fuse is a gR new energy vehicle fuse rated 40A-60A, 450V-500V DC.\r\n<\/code><\/pre>\n
on\u2011board system,charger and wiring\u2011harness comprehensive over\u2011current & short\u2011circuit protection. This series covers rated current 40A\u201160A at 450V \/ 500V DC with 20kA DC breaking capacity. Constructed with special high\u2011temperature\u2011resistant housing,99.99% pure\u2011silver melt and high\u2011purity quartz\u2011sand arc\u2011extinguishing medium. Silver\u2011plated contact surfaces reduce temperature rise and power consumption. It withstands thermal shock,mechanical shock,current impulse and chemical load. Custom time\u2011current performance characteristics are negotiable for special\u2011project demands.<\/p>\n
