Features and Benefits
6
LPS-RK- ⁄10SP
LPS-RK-4SP
• Separate overload and short-circuit elements provide time
delay for close sizing of high inrush loads linked with K1
current-limitation and selective coordination ratio of 2:1
(within Low-Peak fuse family) prevents widespread
blackouts.
• Inventory consolidation of Class RK1, RK5 and H fuses for
reduced SKU investment and minimizing potential for
misapplying fuse.
• 300,000A RMS symmetrical interrupting rating provides
adequate ratings without obsolescence for all electrical
systems, big or small.
• Insulated end caps reduces exposure to live parts and
extends air gap to distance between blades of adjacent
mounted fuses or to housing.

4000A) all containing fusible switches, 500 panel-
boards (100A – 1600A), 75 plug-in busway switches
(100A – 600A), and more than 1900 Cooper
Bussmann Class J Low-Peak® fuses. Cooper
Bussmann LPJ fuses were used because of the
superior series-ratings available using Class J fuses
with downstream circuit breaker panels.
B
Fuses were selected by the consulting engineer for
all switchboards, power panels and busway switches
because of the high available short circuit currents
and the need for selective coordination of
overcurrent protective devices (a requirement of the
New York City Electrical Code) so the electrical
system does not have a “blackouts.”
