Authorized Littelfuse Distributor
Littelfuse KLPC2200 - KLPC series POWR-PRO™ fuses provide ideal overcurrent protection for circuits from 200 through 6000 amperes. KLPC series POWR-PRO™ fuses specification-grade construction and performance meet or exceed the most stringent project specifications: 99.9% pure silver links, silver-plated copper end bells, glass-reinforced melamine bodies, O-ring seals between body and end bells, and granular quartz fillers. KLPC series POWR-PRO™ fuses are the only UL listed Class L fuses that provide a minimum of ten seconds time delay at 500% rated current and are also as current limiting as the fastest Class L fuse on the market. On average, the peak let-through currents of KLPC series fuses are 10% less than any other "time-delay" Class L fuse.

Overview

The Littelfuse KLPC2200 POWR-PRO™ Class L fuse delivers precise overcurrent protection for industrial circuits ranging from 200 to 6000 amperes. Designed for critical power distribution systems, these fuses combine specification-grade construction with superior performance metrics to safeguard high-demand applications. The KLPC2200 features 99.9% pure silver fuse links for consistent conductivity and silver-plated copper end bells for enhanced corrosion resistance. The glass-reinforced melamine body provides exceptional thermal stability and mechanical strength, while O-ring seals between the body and end bells prevent moisture ingress and contamination. Granular quartz fillers optimize arc quenching and thermal management, ensuring reliable operation under fault conditions. A defining advantage of the KLPC2200 is its UL-listed time-delay characteristic, offering a minimum 10-second delay at 500% rated current. This allows temporary inrush currents common in motor starts and transformer energization without nuisance tripping, while still providing rapid response to sustained overloads. The fuse’s current-limiting performance matches the fastest Class L fuses available, with peak let-through currents averaging 10% lower than competing time-delay Class L fuses. This reduces stress on downstream equipment and enhances system safety. The KLPC2200 is ideal for applications requiring robust fault protection, including motor control centers, switchgear, transformers, and power distribution panels. Its compliance with UL Class L standards ensures compatibility with most industrial electrical systems. For projects demanding the highest level of reliability and performance, the KLPC2200 provides a proven solution with measurable benefits in fault current reduction and equipment protection.
