Don't miss a sale or an opportunity to upgrade your fuse protection

Three tiers offer distinct levels of circuit protection

1. Ultimate - Unique element designs deliver a powerful

combination of operating characteristics in one fuse — fast short­circuit protection, current limitation, and time-delay with up to 300
kA interrupting ratings.

2. Advanced - Choose between fast-acting, short-circuit, current

limiting protection or time-delay energy efficient, current limiting
protection based on the application with 200 kA interrupting
ratings.

Compare the minimum melting time-current
characteristics of the fuses with the time­current characteristics of the overload relay

•

Class CC rejection feature, with appropriate fuse block, prevents
inserting lesser-rated supplementary fuses

•

Time-delay coupled with Class CC current-limiting response
provides close sizing on small motor and relay circuits, and
maximum component short-circuit current rating protection

•

200 kA interrupting rating provides high ratings for control circuit
locations

•

Inventory consolidation of 13/32" x 1-1/2" supplemental fuses
reduces SKU investment and minimizes potential for misapplying
fuse

•

Selective coordination ratio of 2:1 (within Low-Peak fuse family)
prevents electrical shutdowns from extending beyond the failed

Features

•

Separate overload and short-circuit elements provide time delay
for close sizing of high inrush loads linked with RK1 current-limita­tion and selective coordination ratio of 2:1 (within Low-Peak fuse
family) helps prevent widespread blackouts

•

Inventory consolidation of Class RK1, RK5 and H fuses for reduced
SKU investment and minimizing potential for misapplying fuse

•

300 kA 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

Typical applications

•

Large distribution switchboards

•

Power panelboards

•

Motor control centers

•
