Not to be confused with Littelfuse's current modern 332 series, ceramic 1/4"x1-1/4" fuses. These are a glass fuses with rejection ears. Type N / 333 are Slow Blow fuses. The fuses were specifically designed to eliminate the possibility of over fusing circuits and only fit Littelfuse 346 series fuse holders Buss HN holders for Type N fuse. Also a combination of three different fuse lengths and seven different widths of bayonet locking tabs on the fuse caps. The fuse post is made to accept only the size amperage range and type (regular or slo blo) in its range. For example: a 1 amp slo blo fuse is 1-1/4" long with .115 to .120 with tabs. The holder used with this will only accept a slo blo fuse (N Type) above 3/4 to 1-1/4 amps.
