Littelfuse JLS030 Class J Time-Delay Fuse - 600V 30A

The Littelfuse JLS030 is a 600-volt, 30-amp Class J time-delay fuse designed for superior circuit protection in commercial and industrial electrical systems. This UL-listed fuse provides reliable overcurrent protection with current-limiting and time-delay characteristics that allow temporary inrush currents while protecting against sustained overloads and short circuits.

Key Features:

• 600VAC voltage rating for industrial applications
• 30-amp current rating with Class J performance specifications
• Time-delay operation prevents nuisance tripping from motor starting and other inrush currents
• Current-limiting design minimizes damage during short-circuit conditions
• Compact 600V Class J dimensions for space-efficient panel installations
• 200kA interrupting rating at 600VAC for robust fault protection
• Non-renewable cartridge construction ensures consistent performance
• UL Listed and meets NEC requirements for branch circuit protection

The JLS Series fuses are ideal for protecting motor circuits, transformers, and general industrial equipment where time-delay protection is essential. The Class J design ensures dimensional interchangeability and rejection features that prevent installation of under-rated fuses.
