JLLS110 - 110 Amp Fuse

JLLS110 - 110 Amp Fuse

The Littelfuse JLLS110 is easy to narrow down when you know the full specification your equipment requires—not simply the amperage printed on the fuse. This 110A Class T fuse combines a fast-acting opening characteristic with a current-limiting design and knife-blade-style construction. For maintenance, replacement, and equipment-matching situations that require exact characteristics, the JLLS110 provides clear specifications you can check before installation. It's built to last, but the key to selecting it correctly is ensuring its electrical ratings and physical configuration match your equipment requirements.

Key Features and Benefits

• 110A continuous current rating: Provides the specific amperage required by equipment designed around a 110-amp Class T fuse.
• Class T fuse: GivesIt'shnicians and buyers an important compatibility checkpoint when identifying the correct fuse.
• Fast-acting opening: Littelfuse specifies the JLLS110 as Fast-Acting (F), making the opening characteristic clear when matching an existing fuse specification.
• Current-limiting design: Part of the JLLS current-limiting fuse family.
• Knife-blade-style construction: The physical design provides another useful checkpoint when matching the fuse to existing equipment.
• Knife-Blade/Bolt-In size: Helps distinguish the JLLS110 from fuses using other physical configurations.
• Non-indicating design: Littelfuse specifies the indicating characteristic as "No."

Material Compliance and Certifications

The manufacturer specifications supplied for the JLLS110 included no specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification information. That does not establish that the product has—or does not have—any particular certification. When a specific listing, approval, or material standard is required, confirm the product markings and the current authoritative Littelfuse documentation rather than assuming compliance.

Where It Works Best

The Littelfuse JLLS110 110A Class T fuse is a logical match for compatible electrical equipment that specifically requires a 110-amp, fast-acting, current-limiting Class T fuse with knife-blade-style construction. It is particularly relevant when the application also calls for the stated 600VAC or 300VDC maximum voltage rating, the corresponding interrupting capacity, and a Knife-Blade/Bolt-In physical configuration. For installations using the manufacturer's specified holder arrangement, the LFT60200 Series PG holder provides an additional compatibility reference.
