Bussmann LPN-RK-2-8/10SP Low-Peak Class RK1 Dual-Element Time-Delay Fuse
The Bussmann LPN-RK-2-8/10SP is a Low-Peak Class RK1 dual-element, time-delay fuse rated 2-8/10A at 250 Vac, 125 Vdc, built for current-limiting circuit protection in large distribution switchboards, power panelboards, and motor control centers. Its ferrule end X ferrule end connection and non-indicating body deliver dependable, code-compliant overcurrent protection, backed by an exceptional interrupt rating of 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc.
Key Features
- Amperage Rating: 2-8/10A for precise circuit protection sizing.
- Class RK1 Construction: Meets Class RK1 fuse standards for reliable current-limiting performance in demanding electrical systems.
- Dual-Element Design: Two internal elements support time-delay response tailored for motor and inrush-current applications.
- Time-Delay Response: Opens in 8 seconds at 500% of rated current, letting normal motor starting surges pass without nuisance opening.
- High Interrupt Rating: 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc for safe operation under high fault-current conditions.
- Ferrule End Connection: Ferrule end X ferrule end termination simplifies installation in standard fuse blocks and holders.
- Electrically Isolated End Cap: Adds a layer of safety during installation and service work.
- Non-Indicating Body: Standard non-indicating fuse construction.
