Conductors can vaporize. Bus barscan break. And components like switchgear, MCCbuckets and motor starters can be destroyed,bringing your operation to a halt.In addition to the current-limiting protection thatsafeguards your equipment, Amp-Trap 2000 fusesoffer you: family includes Class L, Class J, Class RK1 andThat incident can cost your business a milliondollars - or more - in liability. Add to that the costsof dealing with injuries and equipment repair, andyou’re facing a real drain on your profitability.Y O U N E E D T H E C U R R E N TL I M I T I N G P R OT E C T I O N O FA M P -T R A P 2 0 0 0 F U S E STraditional fuses were designed to protect yourelectrical system from fire and explosion, and yourpeople from the potential harm of an arc flash.Mersen’s Amp-Trap 2000 currentlimiting fuses do more than that.Opening in less than one-quartercycle at fault currents up to 300kA,Amp-Trap 2000 fuses minimizethe let-thru current that flowsdownstream.Total system coverage. The Amp-Trap 2000Class CC fuses in a wide range of amperages. It’sthe only one you need to protect your completelow-voltage electrical system, from serviceentrance equipment to your smallest motors. Reduced inventory. Because one Amp-Trap2000 fuse can replace multiple SKUs, you willreduce the number of fuses you use and stock— typically by up to 35%. That means decreasedinventory and operating costs, and less timeordering and stocking. Time-delay. Amp-Trap 2000 fuses withstand highinrush currents from motors and transformersto eliminate nuisance opening. Time-delay alsosimplifies selection and permits the use of smalleramperage ratings, providing better protection incase of overloads. Easy 2:1 selectivity. When a fault occurs, aselective system ensures that the fuse closestNot only do Amp-Trap 2000 fusessave you from arc flash liability,they minimize the downtime thatcan diminish your productivity andprofits. In short, they protect allyour assets.to the fault opens without affecting fuses inupstream circuits, preventing nuisance shutdownsand “blackouts.” With Amp-Trap 2000, selectivityis achieved between any two fuses in series(above 60 amps) when the ratio of upstreamrating to downstream rating is 2-to-1 or greater(see table, page 5). Improved safety. High-energy arc flashes cancreate temperatures of 35,000 F and 1,500pounds per square foot of force. Highly currentlimiting Amp-Trap 2000 fuses protect personneland equipment from these catastrophic effects.And their versatility and rejection-style designhelp to avoid hazardous misapplications. Tomorrow’s protection today. Current-limitingprotection is the wave of the future.
