- Applications
- Features
| Branch Circuit Breaker Panelboard Mains, Industrial Control, Machinery Disconnects and 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 controllers |
| Space saving package for equipment down sizing |
| 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 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, hence 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 |
