Reduces existing fuse inventory by up to 33% IR when upgrading to Low-Peak fuses. 300kA Vac RMS Sym. Consistent 2:1 ampacity ratios for all Low-Peak 100kA Vdc fuses make selective coordination easy. Long time-delay minimizes needless fuse openings Agency information due to temporary overloads and transient surges. UL Listed, Guide JDDZ, File E4273 Current-limitation protects downstream CSA Certified, Class 1422-02, File 53787, components against damaging thermal and Class J per CSA C22.2 No. 248.8 magnetic effects of short-circuit currents. CE Dual-element fuses have lower resistance than ordinary fuses so they run cooler. RoHS compliant Can often be sized for back-up protection against motor burnout from overload or single-phasing if other overload protective devices fail. Proper sizing can provide no damage Type 2 coordinated protection for NEMA and IEC motor controllers.
