KLPC SERIES POWR-PRO® FUSES
600VAC•Time-Delay•200-6000Amperes
Description
KLPC series POWR-PRO® fuses meet or exceed the most
stringent project specifications, such as silver links, silver-plated
copper end bells, glass-reinforced melamine bodies, O-ring seals
between body and end bells, and granular quartz fillers.
Applications
• Switchboard mains and feeders
• Motor control center mains
• Large motor branch circuits
• Protection of power circuit breakers
Features/Benefits
• POWR-PRO Performance (see pg. 3)
• Best in class time-delay withstand
• Current-Limiting
• Easily coordinated with other system components
• 300 kA AC Interrupting Rating (self certified)
