Description
823050
823050 is an S&C Electric SMU-40 fuse unit rated 50 amperes at 25 kV nominal voltage for outdoor distribution applications. This power fuse unit delivers fast, positive fault interruption through high-speed arc elongation in a solid-material-lined bore and efficient deionizing action of gases generated by thermal reaction. The SMU-40 fuse unit is designed for use in SMD-40 power fuse mountings and provides reliable protection in substations and outdoor distribution systems rated up to 34.5 kV. Under maximum fault conditions, heat from the confined arc causes solid material in the arc-extinguishing chamber to undergo thermal reaction, generating turbulent gases that effectively enlarge the bore diameter for mild exhaust release. Under low-to-moderate fault conditions, the arc is extinguished in the small-diameter upper section where deionizing gases are concentrated for efficient arc extinction.
