Branch Circuit Breaker Panelboard Mains, Industrial Control, Machinery Disconnects, Power Panelboards
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 coordinated protection for NEMA and IEC motor controller
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
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 coordination 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 single phasing if other overload protective devices fail
