Protection against overloads and circuit short in electric lines.Rated voltage up to 80V DC or 50Hz 130V AC, Rated current up to 800A.This series of vehicle fuses are made up with two parts, fuse links and fuse bases. According to different applications, the fuse links can be divided into normal type (CNL, RQ1) and fast type (CNN), both bolting connected. The fuse links can be connected directly to an installed fuse base (RQD-2) for convenient fuse exchange.Models, rated voltage and dimensions are shown in figures 16.1~16.4 and table 16.
