Overview
The Bussmann LPS-RK-6SP is an industrial-grade Class RK1 dual element time delay fuse designed for reliable circuit protection in 600VAC and 300VDC applications. This time-delay, dual-element, current limiting fuse has a 6A rating and non-indicating design with interrupting ratings of 300 kA at 600 Vac and 100 kA at 300 Vdc. The dual element construction provides coordinated protection against overloads and short circuits while minimizing nuisance trips in equipment with inrush currents.
Key Features
- Class RK1 fuse with 300 kAIC interrupt rating at 600 Vac and 100 kAIC at 300 Vdc
- Dual element design with 10 second response time at 500% for coordinated branch and feeder circuit protection
- Ferrule-end construction for standard bayonet or screw-based fuse holders
- Current-limiting action reduces fault damage and equipment stress
- Non-indicating fuse with electrically isolated end cap
- Suitable for motors, transformers, solenoids, and general industrial circuits
