▪ Separate   overload and short circuit elements provide time delay for sizing of high   inrush loads linked with class J current limitation

▪ Long   time delay minimizes needless fuse openings due to temporary overloads and   transient surges

▪ Current   limitation protects downstream components against damaging thermal and   magnetic effects of short circuit currents

▪ Dual   element fuses have lower resistance than ordinary fuses, hence they run   cooler

▪ They   can often be sized for back up protection against motor burnout from overload   or single phasing if other overload protective devices fail

▪ Selective   coordination ratio of 2:1 (within Low-Peak® fuse family) prevents electrical   shutdowns from extending beyond the failed circuit

▪ Series   combination ratings with branch circuit breakers allows broad range of   coverage, independent of breaker manufacturer

▪ Proper   sizing can provide "No Damage" type 2 coordinated protection for   NEMA® and IEC® motor controllers

▪ Space   saving package for equipment down sizing

▪ Industry's   only UL listed and CSA Certified fuse with a 300 kA interrupt rating that   allows for simple, worry free installation in virtually any application

▪ Fast   short circuit protection and dual element, time delay performance provide   ultimate protection

▪ Reduces   existing fuse inventory by up to 33% when upgrading to Low-Peak® fuses

▪ Consistent   2:1 ampacity ratios for all Low-Peak® fuses make selective coordination easy
