JLLS003 - 3Amp Fuse

JLLS003 - 3Amp Fuse

The Littelfuse JLLS003 offers specific characteristics for equipment that requires a 3-amp Class T fuse. Rated for 3A continuous current, this industrial cartridge fuse features a fast-acting (F) opening characteristic and a current-limiting design. Littelfuse identifies the LFT60030 Series as the PG holder. In other words, you can verify several concrete specifications instead of relying on appearance or amperage alone. Properly selected, installed, and operated within its stated ratings, the JLLS003 is a purpose-built electrical component designed to last in equipment built for this exact combination of characteristics.

Key Features and Benefits

• 3A continuous current rating: Provides the specific amperage needed when equipment documentation calls for a 3-amp fuse.
• Class T fuse: Clearly defined fuse classification helps with accurate replacement and compatibility checks.
• Fast-acting operation: Littelfuse specifies an F (Fast-Acting) opening characteristic.
• Current-limiting design: Gives you another essential specification to match against the requirements of the electrical equipment.
• 600VAC maximum voltage: Supports compatible AC applications within the manufacturer's stated voltage rating.
• 300VDC maximum voltage: The JLLS003 also carries a defined DC voltage rating for compatible DC applications.
• Industrial cartridge construction: Provides a clearly identified physical format for checking fit and equipment compatibility.
• Non-indicating configuration: Manufacturer specifications identify the JLLS003 as a non-indicating fuse.

Material Compliance and Certifications

The manufacturer specifications supplied for the JLLS003 did not include specific UL, CSA, CE, RoHS, REACH, or other certification or material-compliance information. That does not mean the product lacks any particular approval or compliance status. If a certification or material requirement matters for the installation, confirm it with current authoritative Littelfuse documentation and the markings on the actual fuse.

Where It Works Best

The Littelfuse JLLS003 3A Class T fuse is best suited for compatible electrical equipment that requires a 3A, fast-acting, current-limiting Class T industrial cartridge fuse rated up to 600VAC or 300VDC, as applicable. Its specified fuse block, clip, or holder mounting method also makes the physical installation requirements an important part of the compatibility check.
