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
residential 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 POWR-PRO™ IDSR
Indicator™ fuses for circuits between 250 and 600 volts. The user gets
all the benefits of time-delay RK5 fuses plus the added benefits of a n
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.
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.
