The screwed fuse of the Eaton Bussmann series is essentially a fuse with brackets with which the fuse can be screwed onto a fuse holder. This type of security is mainly used as a "weak point" in plants. They are designed to break if a fault such as overcurrent or short circuit occurs - they are a safety and damage measure. Cooper Bussman fuses are commonly found in a variety of industrial applications, electrical devices and cable systems
Strengths
Good peak and let-through current limitation 1:1.6 Selective coordinate ratio between ‘minor’ and ‘major’ fuse gM type offer enhanced motor starting capability Power loss values well within the limits of IEC 60269-2
