Circuit Protection Products
Ferraz Shawmut announces its Amp-Trap 2000 family of Type “2” circuit protection products with current-limiting fuses that prevent high-energy arcs that can stop production, damage HVAC equipment and shut down lighting and communications. Opening in less than one-quarter cycle at fault currents up to 300 kA, these fuses minimize the let-through current that flows downstream. The fuses feature time delay, handling inrush currents from motor starters and transformers without nuisance opening, and 2:1 selectivity to avoid nuisance shutdowns and blackouts. A4BQ fuses provide optimal over-current protection for service entrances, large motors, feeders and other circuits. They are designed for applications requiring fuses greater than 600A.
