* NLKP series available only in those amperages preceded

by an asterisk.

Refer to Fuse Block section of this catalog for additional

information.

NLN/NLS Class K5 Fuses

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.

However, to obtain the added benefits of time-delay, current-

limitation, and higher interrupting rating, consider the use of

250 and 600 volts. The user gets all the benefits of time-delay

RK5 fuses plus the added benefits of an indicating fuse that

tells when it has opened. Complete information on these

catalog. For circuits up to 250 volts, see FLNR fuses in this

section of the catalog.

APPLICATIONS

General purpose residential and commercial circuits with

little or no motor load.

Resistive heating loads.

ECONOMICAL

I

For use in applications where lowest initial cost is the

major consideration.

50,000 A.I.R., Class K5 — Adequate interrupting capacity

for residences and many smaller facilities.

AMPERE RATINGS

NOTE: NLKP series fuses have limited interrupting rating and

should be used only where available short circuit current is

known to be less than the fuse interrupting rating. Where

available fault current is unknown, where it exceeds NLN/NLS

interrupting rating, or where it may increase in the future,

fuses provide superior protection for all motor and general

purpose circuits containing inductive loads.
