Description
121050R3
121050R3 is an S&C Electric SM-4 Refill Unit Power Fuse designed for outdoor substation applications with a continuous current rating of 50E amperes at 14.4 kV nominal voltage. This refill unit features a silver or pretensioned nickel-chrome current-responsive fusible element with solderless, brazed terminal construction for reliable fault interruption. The SM-4 series utilizes high-speed arc elongation in a solid-material-lined bore combined with efficient deionizing action to achieve fast, positive fault interruption across a range of fault magnitudes. The precision-drawn fusible element provides melting time-current characteristics with only 10% total tolerance in melting current, ensuring superior coordination with protective relays and other fuses compared to standard fuses with 20% tolerance.
