Bussmann LPJ-400SP

• Separate overload and short circuit elements provide time delay for sizing of high inrush loads linked with class J current limitation
• 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 co-ordinated protection for NEMA and IEC motor controllers
• Space saving package for equipment downsizing
• 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 co-ordination easy
• 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 so they run cooler
• They can often be sized for back up protection against motor burnout from overload or 1 ph if other overload protective devices fail

Bussmann's UL Class J fuse products extend both our Low-Peak family of products with our LPJ_SP and LPJ_SPI dual-element, time-delay fuses as well as our Limitron line offering fast-acting JKS fuses. The LPJ fuses provide industry leading 300,000 amp interrupting rating at 600Vac RMS Sym and 100kA Vdc while delivering a minimum of 10 seconds of 500% rated current ride-through performance which is ideal for sizing of high inrush loads. The LPJ products are available with optional permanent replace fuse indication. These UL Class J products in sizes 1 to 600 amps provide exceptional performance at 600 Vac and 300 Vdc (see spec sheets for specific details) in a compact size rejecting footprint
