LLNRK009 - 9Amp Fuse

LLNRK009 - 9Amp Fuse

When you're protecting an electrical circuit, the right fuse makes all the difference. It's not just about matching the amperage; voltage limits, fuse classification, time-delay characteristics, and short-circuit interrupting capacity are equally important. The Littelfuse LLNRK009 is a 9-amp, Class RK1 time-delay fuse from the Littelfuse POWR-PRO series, engineered to provide overload and short-circuit protection in compatible electrical distribution systems.

Key Features and Benefits

• 9A continuous current rating: Provides overcurrent protection for circuits specifically designed to use a 9-amp fuse with matching electrical characteristics.
• Class RK1 fuse classification: Designed for applications requiring Class RK1 protection characteristics and compatible fuse mounting equipment.
• 250VAC maximum voltage rating: Suitable for compatible AC electrical circuits operating within the manufacturer's stated voltage limit.
• 125VDC maximum voltage rating: Supports compatible DC applications where a 9A Class RK1 time-delay fuse is specified.
• Non-indicating construction: Features a straightforward fuse design without an integrated blown-fuse indicator.
