Littelfuse FLNR005 Class RK5 Fuse 5A 250V Slo-Blo Time Lag Industrial Cartridge

Engineered for superior performance, the FLNR005 from Littelfuse is an essential component for ensuring the protection of fully-rated panelboards and load centers. It excels in managing both individual fused combination motor controllers and general-purpose circuits, with a remarkable interrupting rating of 20,000A at 125VDC. This device stands out thanks to its automated, precision-manufactured components that guarantee a consistent and accurate response to overloads and short circuits, enhancing the safety and reliability of your industrial control panels. Designed to deliver faster-acting short circuit protection than traditional non-current limiting mechanical devices, it can reliably interrupt all overcurrents up to 200,000 amperes. This capability is crucial for motor control center mains and branch circuits, service entrance switches, and switchboard main and feeder switches, making it a versatile solution for various high-demand applications. With its Slo-Blo/Time Lag opening mechanism, the FLNR005 ensures that your electrical systems remain safeguarded against potential faults, emphasizing its importance in modern electrical infrastructure.
