GFEVT1000\u201138R ev dc fuse<\/strong> is aR\u2011class high\u2011speed bolt\u2011mount DC fuse dedicated for energy\u2011storage systems and EV battery\u2011pack protection. Rated 250A\u2011400A at 1000V DC with 50kA high breaking capacity and time\u2011constant \u22645\u202fms. It uses M8 mounting bolt with recommended installation torque 12\u00b11.0\u202fN.m. The fuse supports parallel installation for higher ampacity within dimensional guidelines. It delivers superior anti\u2011shock & anti\u2011vibration performance \u226520g acceleration. For high\u2011altitude applications between 2000\u20114500\u202fm, derating for rated\u2011current and insulation distance correction shall be considered. Manufactured to IEC60269.4, UL248\u201113, JASO\u2011D622 standards, CE marked, RoHS\u2011compliant, REACH declaration available upon request.<\/p>\n
