Cooper Bussmann LPS-RK-10SP Low-Peak Class RK1 Time-Delay Fuse 10A 600V The Cooper Bussmann LPS-RK-10SP is a 10-amp, 600-volt, Class RK1 dual-element time-delay fuse designed to provide superior protection for various electrical applications. Its advanced features ensure reliable performance and enhanced safety in demanding environments. Key Features Dual-Element Design: Incorporates separate overload and short-circuit elements, offering precise time-delay characteristics that allow for close sizing with high inrush loads. Time-Delay Performance: Provides a minimum of 10 seconds delay at 500% of rated current, accommodating temporary surges without unnecessary interruptions. High Interrupting Rating: Capable of interrupting up to 300,000 amperes at 600 VAC and 100,000 amperes at 300 VDC, ensuring robust protection against high fault currents. Current Limiting: Limits the let-through energy during short-circuit events, protecting downstream components from thermal and magnetic damage. Insulated End Caps: Reduces exposure to live parts and increases the air gap between adjacent fuses, enhancing safety and minimizing the risk of electrical arcing. Selective Coordination: Consistent 2:1 ampacity ratios facilitate easy selective coordination, preventing widespread outages by isolating faults to specific circuits. Applications The LPS-RK-10SP fuse is ideal for protecting a wide range of electrical equipment, including: Large distribution switchboards Power panelboards Motor control centers Machinery disconnect switches Motors and transformers Solenoids and general-purpose circuits Specifications Amperage Rating: 10 A Voltage Rating: 600 VAC / 300 VDC Interrupting Rating: 300 kA at 600 VAC; 100 kA at 300 VDC Response Time: 10 seconds at 500% of rated current Dimensions: 0.81 inches in diameter x 5.00 inches in length Connection Type: Ferrule end x ferrule end Compliance: UL Listed, CSA Certified, CE Marked Benefits Enhanced Safety: High interrupting capacity and current-limiting features protect equipment and personnel from electrical faults. Operational Efficiency: Time-delay characteristics allow for the accommodation of temporary inrush currents, reducing unnecessary downtime. Inventory Reduction: The ability to replace multiple fuse types with a single Low-Peak fuse simplifies inventory management and reduces costs. The Cooper Bussmann LPS-RK-10SP fuse combines advanced protection features with practical design elements, making it a reliable choice for safeguarding electrical systems in various industrial and commercial applications.
