Agency Information: CE, UL Listed – Special Purpose*,
Guide JFHR, File E56412, CSA Certified (200,000 AIR),
Cl RK1 per CSA C22.2, No. 248.12, Cl 1422-02, File
53787.
Features and Benefits
? 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 Cl 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 all.
? Insulated end caps reduces exposure to live parts and
extends air gap to distance between blades of adjacent
mounted fuses or to housing.
