Littelfuse JTD070ID 70 Amp 600V Class J Time-Delay Fuse

The Littelfuse JTD070ID is a Class J time-delay fuse designed for reliable overcurrent protection in industrial and commercial electrical systems. Rated for 70 amperes at 600 volts AC, this current-limiting fuse provides superior short-circuit protection while allowing temporary harmless inrush currents associated with motor starting and transformer energization.

Key Features:

• 70 amp current rating with 600 volt AC capacity
• Time-delay characteristics prevent nuisance tripping during motor startup
• Current-limiting design for enhanced short-circuit protection
• Class J configuration with rejection-style dimensions for proper fuse holder compatibility
• 200,000 amp interrupting rating at 600V AC
• UL Listed and CSA certified for safety compliance
• Suitable for motor circuits, feeders, and general distribution panels

Class J time-delay fuses are ideal for applications requiring both motor overload protection and robust short-circuit interruption. The rejection-style blade design ensures that only proper amperage-rated fuses can be installed in compatible holders, preventing dangerous oversizing.
