Branch Circuit Breaker Panelboard Mains, Industrial Control, Machinery Disconnects, Power Panelboards
Space-saving package for equipment downsizing
Industry's only UL Listed and CSA Certified fuse with a 300kA interrupting rating that allows for simple, worry-free installation in virtually any application
Separate overload and short circuit elements provide time delay for sizing of high inrush loads linked with Class J current limitation
Fast short circuit protection and dual-element, time-delay performance provide ultimate protection
Selective coordination ratio of 2: 1 (within low peak fuse family) prevents electrical shutdowns from extending beyond the failed circuit
Reduces existing fuse inventory by up to 33% when upgrading to low peak fuses
Series combination ratings with branch circuit breakers allows broad range of coverage, independent of breaker manufacturer
Consistent 2:1 ampacity ratios for all low peak fuses make selective coordination easy
Proper sizing can provide "no damage" Type 2 coordinated protection for NEMA and IEC motor controller
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 single phasing if other overload protective devices fail
