LLNRK007 - 7Amp Fuse

LLNRK007 - 7Amp Fuse

Reliable electrical protection starts with choosing the right fuse for the job. It's not just about matching the amperage. Voltage ratings, time-delay characteristics, interrupting capacity, and fuse classification all play a key role in protecting electrical equipment from overloads and short circuits. The Littelfuse LLNRK007 is a 7-amp Class RK1 time-delay fuse from the Littelfuse POWR-PRO series, designed for use in compatible electrical distribution systems.

Key Features and Benefits

• 7A continuous current rating: Provides overcurrent protection for compatible electrical circuits requiring a 7-amp fuse.
• Class RK1 fuse classification: Designed for applications that specify Class RK1 fuse characteristics, including compatible electrical distribution equipment.
• 250VAC maximum voltage rating: Supports compatible AC electrical applications operating within the fuse's specified voltage limits.
• 125VDC maximum voltage rating: Provides an option for properly specified DC circuits requiring a 7A time-delay fuse.
• Non-indicating construction: Features a straightforward design without a built-in blown-fuse indicator.
