American Stand. Fuses & Fuse Holders

American Stand. Fuses & Fuse Holders
American Standard fuses are used in electrical systems in the USA, Canada and South America. In Australia & NZ, they are predominantly sourced as replacement parts for imported American equipment. They are manufactured to UL and CSA standards and the industrial versions are classified according to the following classes: T, J, L, RK5 & RK1. American Standard semiconductor fuses are popular solutions in many applications as are the compact midget fuses used to protect multimeters and various lower current applications.
