Bussmann® Low-Peak® LPS-RK-400SP Low Voltage Current Limiting Time Delay Fuse, 400 A, 600 VAC, 300 VDC, 100/300 kA, Class RK1, Cartridge Body
SKU: BUSLPS-RK-400SP
Manufacturer Part Number: LPS-RK-400SP
UPC: 051712548557
Features
- Separate overload and short circuit elements provide time delay for close sizing of high inrush loads linked with RK1 current limitation and selective co-ordination ratio of 2:1 prevents widespread blackouts
- Time delay permits 130% FLA sizing for backup motor protection
- 300 kA rms symmetrical interrupt rating provides adequate ratings without obsolescence for all electrical systems, big or small, allows for simple, worry free installation in virtually any application
- 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
- Current limitation protects down stream components against damaging thermal and magnetic effects of short circuit currents
- Protects against 1-phase motor damage
- Proper sizing can provide "no damage" type 2 co-ordinated protection for NEMA and IEC motor controllers
- Electrically isolated end cap
- 10 s at 500% of rated current response time
- 300 kA at 600 VAC, 100 kA at 300 VDC interrupt rating
