JLLN001 - 1 Amp Fuse

JLLN001 - 1 Amp Fuse

If you're replacing a JLLN001 fuse, check a few numbers before calling it a match. This Littelfuse JLLN Series fuse is rated at 1 amp, with maximum voltage ratings of 300VAC and 160VDC. You can mount the JLLN001 using a compatible fuse block, clip, or holder, and Littelfuse identifies the LFT30030 Series as its PG holder. Put those details together, and you have a very specific fuse—not simply a generic 1-amp replacement. For existing equipment that calls for these characteristics, the JLLN001 gives you clear specifications to work from and is built to last within its intended application.

Key Features and Benefits

• 1A continuous current rating — An exact specification that's easy to compare with the requirements of your equipment.
• Fast-acting operation — The JLLN001 carries an "F" opening designation for fast-acting operation.
• Current-limiting Class T design — Useful when your application specifically requires this fuse class and characteristic.
• 300VAC / 160VDC maximum ratings — Both AC and DC voltage limits are clearly defined.
• Industrial cartridge style — Gives you another physical characteristic to check when confirming compatibility.
• Non-indicating design — No visual fuse-status indicator is specified.

Material Compliance and Certifications

The manufacturer data supplied for this exact JLLN001 did not include specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification information. Rather than assume that a certification applies across a product family, check the markings or current manufacturer documentation when a particular approval or compliance standard is required.

Where It Works Best

The Littelfuse JLLN001 makes sense for compatible equipment that specifically calls for a 1A Class T fuse with fast-acting, current-limiting characteristics. Its combination of 300VAC and 160VDC maximum voltage ratings, industrial cartridge construction, and defined AC/DC interrupting ratings gives maintenance personnel and electricians several concrete points to check when identifying the correct fuse.
