  • Recommended for Arc Flash energy reduction
  • Pure silver links ensure lowest let-thru current and longer fuse life
  • Easy 2-to-1 selectivity for prevention of nuisance shutdowns and “blackouts”
  • Rejection-style design prevents replacement errors
  • High-visibility orange label gives instant brand recognition

  • Metal-embossed date and catalog number for traceability and lasting identification
