One Time Fuses - Class H & K

Fuseco is one of the largest stocking distributors of one-time fuses from manufacturers such as Mersen, formerly known as Ferraz Shawmut, Cooper Bussmann, Littelfuse and more. Technically, any non-renewable fuse can be considered a one-time fuse. However the term one-time fuse most often refers to UL Class H fuses and to fast acting Class K5 fuses. These fuses are not current-limiting and do not have a rejection feature. Sometimes one-time fuses are referred to as "Code" fuses.
