Special purpose rating of 300,000 AIR. General Information: All-purpose silver-linked fuse for both overload and shortcircuit protection for high capacity systems (mains and large feeders). Time-delay (minimum of four seconds at five times amp rating) for close sizing. Current-limiting action of the fuse generally affords considerable reduction in bus bracing. Interrupting rating of 300,000 amperes complies with NEC Sections and for day s large capacity systems. O-ring seals maximize pressure build-up during currentlimiting action and ensure filler retention. High grade silica-sand filler; accelerates response of fuse short-circuits by having quenching effect upon the fuse arc. 99.9% pure silver fuselinks. The high conductivity of silver gives low watt loss and low operating temperature at normal current levels; maximizes tal clearing I 2 t fault energy let-through. Selective coordination (blackout prevention). Glass melamine tube. Silver-plated end bells. CE logo denotes compliance with European Union Low Voltage Directive ( VAC, VDC).
