• Minimize Damage - Class J fuses can provide Type II "No Damage" protection to IEC and NEMA components.
• Time Delay - Will handle repeated motor start-ups without nuisance opening.

The Class J JLS fuse features:

• Extremely current-limiting design often permits use of readily available, less costly equipment.
• Manufacturers of equipment containing dual voltage devices can simplify manufacturing and reduce inventory by standardizing on 600 volt JLS fuses and Class J fuse blocks for all AC voltage ratings.
• 200,000 A.I.R. rating minimizes need for short-circuit calculations.
