KLLU Class L Fuses

600 VAC • Time-Delay • 601 – 4000 Amperes

KLLU series UL Listed, time-delay, Class L fuses are quality fuses,

developed to provide a somewhat lower priced alternate to the

POWR-PRO

all UL requirements for Class L fuses. For superior protection and

performance, specification-grade POWR-PRO KLPC series fuses are

the recommended fuse. Complete information on KLPC fuses may

be found in the POWR-PRO Fuse section of this catalog.

can seldom be 100% coordinated, KLLU series fuses permit use of a

wider range of breaker setting than fast acting Class L fuses.

Excellent protection for a single breaker or a group of breakers.
