Information About LPS-RK-400SP
The LPS-RK-400SP is a dual-element fuse from the Eaton Bussmann LPS-RK series engineered for high-performance circuit protection. It is constructed as a Class RK1 fuse with blade-style terminations, allowing secure installation in compatible fuse holders and disconnects. The fuse incorporates time-delay characteristics to tolerate temporary inrush currents while maintaining strong current-limiting response during fault conditions. It is commonly applied in power distribution systems operating at up to 600 VAC or 300 VDC where selective coordination and high interrupting capacity are required.
Key Features
- Class RK1 construction: Provides high interrupting capacity and enhanced current-limiting performance compared to RK5 fuses.
- 400 amp current rating: Supports high-load circuits in industrial and commercial electrical systems.
- Dual-element time-delay design: Allows temporary overloads such as motor starting currents without nuisance operation.
- High interrupting ratings: Safely interrupts up to 300 kA at 600 VAC and 100 kA at 300 VDC.
- Blade end connections: Ensures stable electrical contact in standard fuse holders and switchgear.
- Non-indicating configuration: Maintains simple mechanical design without visual fuse status indication.
- AC and DC compatibility: Designed for use in systems operating at both alternating and direct current voltages.
The LPS-RK-400SP delivers the reliability and precision required for selective, high-capacity overcurrent protection in industrial and commercial power distribution systems.
