Midget fuses are considered as supplementary fuses designed to provide reliable assistance for better overcurrent protection. They have a standard 10x38mm size, which is why it is sometimes called 10x38mm fuse. However, the volt and amp ratings can vary from one midget fuse model to another. Since they are small or have a midget size, midget fuses are mainly for internal component protection. They are applicable for small motors and control circuit wiring. Popular midget fuse brands like Bussmann are for sale at MRO Supply. They come in varying ampere ratings and measurements to satisfy your application requirements.
