JLLS070 - 70Amp Fuse

JLLS070 - 70Amp Fuse

The Littelfuse JLLS070 is your reliable 70-amp Class T fuse known for its fast-acting performance and current-limiting features. With ratings of 600VAC and 300VDC, it suits a wide range of applications. Its impressive interrupting capacity—200,000A at 600VAC and 20,000A at 300VDC—ensures safety under fault currents.

Key Features and Benefits

• 70A continuous current rating: Matches applications specifically requiring a 70-amp fuse.
• Class T fuse: Provides an important compatibility checkpoint for equipment designed around Class T fuses.
• Fast-acting opening: Littelfuse specifies the JLLS070 as Fast-Acting (F).
• Current-limiting characteristics: Identified by the manufacturer as part of its current-limiting family style.
• 600VAC maximum voltage: Supports compatible AC applications within the fuse's specified ratings.
• 300VDC maximum voltage: Provides a clearly defined DC rating for compatible equipment.
• Knife-blade construction: The manufacturer's disclaimer identifies knife-blade-style construction, while the size specification is Knife-Blade/Bolt-In.
• Non-indicating: No indicating function is specified for this model.

Where It Works Best

The Littelfuse JLLS070 70A Class T fuse is a logical match for compatible electrical equipment that specifically requires a 70A, fast-acting, current-limiting Class T fuse with knife-blade-style construction. It is particularly relevant when the equipment specifications call for the JLLS070's combination of 600VAC or 300VDC capability, corresponding interrupting ratings, and Knife-Blade/Bolt-In physical format. The specified LFT60100 Series PG holder gives you another useful detail to verify when checking the application.
