JLLN1000 - 1000Amp Fuse Description
JLLN1000 - 1000Amp Fuse
When you're selecting a 1000-amp fuse, consider the full specifications, not just the amperage. The Littelfuse JLLN1000 is a Class T, fast-acting fuse with a knife-blade/bolt-in design, perfect for secure mounting in compatible holders, like the LSCR Series. This non-indicating fuse is ideal for equipment requiring this specific catalog number and configuration.
Key Features and Benefits
- 1000A continuous current rating: Clearly identifies the amperage for applications requiring a 1000-amp fuse.
- Class T fuse: Provides a specific fuse-class designation that can be checked directly against equipment requirements.
- Fast-acting opening characteristic: Littelfuse specifies the JLLN1000 as Fast-Acting (F).
- Current-limiting design: Part of the manufacturer's current-limiting fuse family.
- 300VAC maximum rating: Suitable for compatible AC applications requiring a fuse rated up to 300VAC.
- 125VDC maximum rating: Also specified for compatible DC applications up to 125VDC.
- Knife-blade/bolt-in construction: Provides an important physical characteristic to check when matching the fuse with existing equipment.
- Non-indicating configuration: Manufacturer specifications identify the JLLN1000 as a non-indicating fuse.

Material Compliance and Certifications
The supplied manufacturer information for the Littelfuse JLLN1000 does not specify UL, CSA, CE, RoHS, REACH, or other certification or material-compliance details. These should not be assumed from other JLLN products or similar-looking Class T fuses. If the application requires a particular certification or compliance standard, confirm it using the markings and authoritative documentation for the exact JLLN1000 catalog number.
Where It Works Best
The JLLN1000 1000A Class T fuse is best suited to compatible electrical equipment designed around its 1000A continuous current, 300VAC or 125VDC maximum voltage, fast-acting operation, current-limiting characteristics, and knife-blade/bolt-in construction. It is a particularly clear match to evaluate when existing equipment documentation identifies JLLN1000 or specifies equivalent electrical and physical requirements.
