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 residen-
tial 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.
* NLKP series available only in those amperages preceded
by an asterisk.
Example part number (series & amperage): NLS 125
However, to obtain the added benefits of time-delay, current-
limitation, and higher interrupting rating, consider the use of
POWR-PRO® IDSR IndicatorTM fuses for circuits between
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
fuses may be found in the POWR-PRO® section of this
catalog. For circuits up to 250 volts, see FLNR fuses in this
section of the catalog.
RECOMMENDED FUSE BLOCKS
LH250 series (for NLN and NLKP series fuses)
LH600 series (for NLS series fuses)
Refer to Fuse Block section of this catalog for additional infor-
mation.
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,
200,000 ampere interrupting rating Littelfuse POWR-PROTM
IDSR IndicatorTM fuses and FLNR/FLSR series fuses provide
superior protection for all motor and general purpose circuits
containing inductive loads.
APPLICATIONS
General purpose residential and commercial circuits with little
or no motor load.
Resistive heating loads.
ECONOMICAL
ꢀ
For use in applications where lowest initial cost is the major
consideration.
SAFETY
ꢀ
50,000 A.I.R., Class K5 — Adequate interrupting capacity
for residences and many smaller facilities.
