JLLS090 - 90Amp Fuse

JLLS090 - 90Amp Fuse

The Littelfuse JLLS090 is a clearly specified 90-amp Class T fuse for your applications that require a matching electrical and physical configuration. It combines fast-acting operation with a current-limiting family style and carries maximum voltage ratings of 600VAC and 300VDC.

Key Features and Benefits

• 90A continuous current rating: Matches equipment requiring a 90-amp fuse with the other JLLS090 specifications.
• Class T fuse: Provides a defined fuse class for more precise compatibility checking.
• Fast-acting opening characteristic: Littelfuse specifies the JLLS090 as Fast-Acting (F).
• Current-limiting family style: Delivers the current-limiting characteristic identified for this JLLS Series fuse.
• 600VAC maximum voltage: Supports compatible AC applications within the manufacturer's stated ratings.
• 300VDC maximum voltage: Provides a defined DC rating for equipment requiring the corresponding specifications.
• Knife-blade construction: The Knife-Blade/Bolt-In configuration provides an important physical checkpoint when matching the fuse to existing equipment.
• Non-indicating design: The JLLS090 is specified as a non-indicating fuse.

Material Compliance and Certifications

The supplied manufacturer specifications for the JLLS090 included no specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification information. That does not establish the presence or absence of any particular certification. When a specific installation requires an approval or material standard, verify the product markings and consult current authoritative Littelfuse documentation.

Where It Works Best

The Littelfuse JLLS090 90A fuse suits compatible electrical equipment that requires a 90A Class T, fast-acting, current-limiting fuse with knife-blade-style construction. It's a logical part to evaluate for equipment calling for the JLLS090 catalog number, 600VAC or 300VDC maximum voltage ratings, the applicable interrupting capacity, and a Knife-Blade/Bolt-In configuration. The specified LFT60100 Series PG holder provides another useful reference point when checking an existing installation.
