NLN/NLS Class K5 Fuses
250/600 VAC • “One-Time” • 1 – 600 Amperes
NLN and NLS series fuses provide low cost protection for general purpose
feeder and branch circuits when available short-circuit currents are less
than 50,000 amperes. They replace all Class H fuses which have only a
10,000 ampere interrupting rating. They are suitable for use in many resi-
dential and smaller commercial and industrial applications.
NLKP series fuses are Canadian “Code” fuses specifically designed to
meet Canadian Electrical Code Type P fuse requirements for residential
use. They have a 10,000 ampere interrupting rating.

fuse that shows when it has opened. Complete information on these
fuses may be found in the POWR-PRO fuse section of this catalog. For
