Features and Benefits
• 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) prevents widespread
blackouts.
• Inventory consolidation of Class RK1, RK5 and H fuses for
reduced SKU investment and minimizing potential for
misapplying fuse.
• 300kA 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.
