Cooper Bussmann introduces Low-Peak fuses

May 22, 2008

ST. LOUIS, May 22, 2008 – Electrical reliability and safety are critical for productivity, and protecting personnel and equipment. To help meet these objectives Cooper Bussmann has created the Low-Peak family of current-limiting fuses for use in main, feeder and branch circuits (up to 600V), or for supplemental protection in equipment, panels or assemblies. Unlike circuit breakers, Cooper Bussmann Low-Peak fuses are the overcurrent protection solutions that never require maintenance or calibration – providing constant, reliable performance.Cooper Bussmann Low-Peak fuses provide:More downtime reduction. Users receive Type 2 “No Damage” motor starter/controller protection plus faster troubleshooting with fuse indication. Low-Peak fuses are available in Class L, J, CC and RK1 to meet virtually all system protection needs.More workplace safety. The current-limiting Low-Peak fuse minimizes incident energy to reduce arc-flash hazards to the lowest levels possible. Interrupting ratings up to 300kA minimize the worst fault current conditions. Plus, the Low-Peak CUBEFuse is IP20 finger-safe.More Code compliance. Low-Peak fuses help reduce fault currents to meet new assembly Short-Circuit Current Rating (SCCR) requirements for equipment installations. And selective coordination is easy with a 2:1 amp ratio between upstream and downstream fuses.All with less inventory and cost. Consolidating to Low-Peak fuses reduces inventory by up to 33 percent. Users get less waste, less confusion with fewer dollars tied up. A simplified inventory of Cooper Bussmann Low-Peak fuses (and other Cooper Bussmann fuses for special requirements) reduces the number of fuses users have to stock, buy and track – and minimizes fuse replacement errors.Upgrade & Save:Customers can find out how much reduced inventory and increased savings they will achieve by sending Cooper Bussmann their current fuse inventory and use data. Cooper Bussmann will provide analysis and a recommended fuse consolidation Low-Peak Upgrade – along with a savings summary within seven business days.
