LLNRK005 - 5Amp Fuse

LLNRK005 - 5Amp Fuse

The right fuse does more than match the amperage printed on the original component. It needs to match the circuit's voltage, fuse class, opening characteristics, and available fault current. The Littelfuse LLNRK005 is a 5-amp Class RK1 time-delay fuse from the Littelfuse POWR-PRO series, designed to provide overload and short-circuit protection in your compatible electrical systems.

Key Features and Benefits

• 5A continuous current rating: Provides overcurrent protection for compatible circuits requiring a 5-amp fuse.
• Class RK1 fuse classification: Designed for applications specifying Class RK1 overcurrent protection.
• 250VAC and 125VDC ratings: Supports compatible AC and DC electrical applications within the manufacturer's specified limits.
• Non-indicating design: The manufacturer identifies this as a fuse without a built-in blown-fuse indicator.
• Fuse block, clip, and holder mounting: Fits compatible fuse mounting equipment.
