FeaturesFast short circuit protection and dual element, time delay performance provide ultimate protectionSeparate overload and short circuit elements provide time delay for close sizing of high inrush loads linked with RK1 current limitationSelective coordination ratio of 2:1 (within Low-Peak™ fuse family) prevents widespread blackoutsInventory consolidation of class RK1 fuses for reduced SKU investment and minimizing potential for misapplying fuse300 kA RMS symmetrical interrupting rating provides adequate ratings without obsolescence for all electrical systems, big or smallInsulated end caps reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housingTime delay permits 130% FLA sizing for back-up motor protectionCurrent limitation protects downstream components against damaging thermal and magnetic effects of short circuit currentsProtects against single phase motor damageProper sizing can provide "No Damage" type 2 coordinated protection for NEMA and IEC motor controllers300 kA (RMS symmetrical) at 600 VAC, 100 kA at 300 VDC interrupt rating10 sec (minimum) at 500% of rated current time delay
