Description
Eaton Bussmann series LPS-RK fuse – Low-Peak RK1 Time-Delay Fuse
The Eaton Bussmann series LPS-RK fuse is a Class RK1 dual element, current-limiting, time-delay fuse designed for low voltage applications up to 600 Vac and 300 Vdc. It provides ultimate protection for feeder and branch circuits, motors, transformers, solenoids, and general purpose circuits. This fuse is suitable for electrical distributors and switchgear suppliers requiring reliable overcurrent protection with high interrupting ratings and time-delay performance.

Features
- Dual-element design provides fast short-circuit protection with time-delay for temporary overloads
- Current-limiting capability reduces damaging thermal and magnetic effects downstream
- High interrupting rating (300 kA at 600 V AC, 100 kA at 300 V DC) allows safe installation in virtually any application
- Consistent 2:1 ampacity ratios simplify selective coordination
- Time-delay permits 130% full load amperage sizing for motor backup protection
- Reduces fuse inventory by up to 33% when upgrading to Low-Peak fuses
- Protects against single-phase motor damage and supports “no damage” Type 2 coordinated protection for NEMA and IEC motor controllers
