- Applications
- Features
| Branch Circuit Breaker Panelboard Mains, Industrial Control, Machinery Disconnects and Power Panelboard Applications |
| 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 |
