Ceramic high\u2011temp fork bolt\u2011down short\u2011circuit protector is a heavy\u2011duty DC protective device compliant with ISO 20934 Special Purpose Fuses. Equipped with high\u2011temperature\u2011resistant ceramic shell and tin\u2011plated copper\u2011alloy terminals, this protector adopts dual M8 bolt installation with 51\u202fmm hole centre\u2011to\u2011centre spacing. Important note: This is a short\u2011circuit\u2011only protector and cannot provide overload\u2011protection.<\/strong> It is designed for 70V DC heavy\u2011current circuits in new\u2011energy vehicles, marine equipment and energy\u2011storage battery systems.<\/p>\nCore Features<\/h2>\n
