445007R1 - S&C Electric SMD-1A 7 Amp 46 kV Power Fuse Unit

445007R1

445007R1 is an S&C Electric SMD-1A power fuse unit rated 7 amperes at 46 kV nominal voltage, designed for outdoor distribution substations and power line protection applications.

The SMD-1A fuse unit features a solid-material-lined bore that enables fast, positive fault interruption through high-speed arc elongation and efficient deionizing action. The fusible element uses silver or pretensioned nickel-chrome current-responsive material drawn to precise diameters with solderless, brazed terminal construction. This design delivers melting time-current characteristics with only 10% total tolerance in melting current, providing reliable overcurrent protection for transformers, capacitor banks, and cables in outdoor distribution systems.
