General Information:
• KLU Limitron®general purpose copper link fuses.
• Copper links result in a minimum 5 second time-delay at
500% ampere rating.
• Current-limiting – provides component short-circuit
protection.
• 200,000 AIR complies with NEC Sections 110-9 and
230-65 in today’s large capacity systems.
• Selective coordination (blackout prevention).
• No fuse reducers available. See KRP-CL.
