Agency Information: CE, UL Listed – Special Purpose*,

Guide JFHR, File E56412, CSA Certified (200,000 AIR),

Class RK1 per CSA C22.2, No. 248.12, Class 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 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.
