- Fast short circuit protection and dual element, time delay performance provide ultimate protection
- Insulated end caps reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing
- Current limitation protects downstream components against damaging thermal and magnetic effects of short circuit currents
- 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 co-ordination easy
- Time delay permits 130% FLA sizing for back-up motor protection
- Inventory consolidation of class RK1/RK5/H fuses for reduced SKU investment and minimizing potential for misapplying fuse
- Separate overload and short circuit elements provide time delay for close sizing of high inrush loads linked with RK1 current-limitation and selective co-ordination ratio of 2:1 (within Low-Peak fuse family) helps prevent widespread blackouts
- Protects against 1 ph motor damage
- Proper sizing can provide "no damage" type 2 co-ordinated protection for NEMA and IEC motor controllers
- Electrically isolated end caps for additional safety
