JLLN225 - 225Amp Fuse

JLLN225 - 225Amp Fuse

The Littelfuse JLLN225 brings together the specifications that matter when your equipment calls for a 225-amp Class T fuse. For electrical equipment designed around these exact characteristics, the JLLN225 offers a clearly defined component built to last when properly selected, installed, and operated within its specified ratings.

Key Features and Benefits

• 225A continuous rating: Provides the specific current rating needed when equipment documentation calls for a 225-amp fuse.
• Class T fuse: Gives maintenance teams and buyers a clear fuse classification to verify against the equipment requirements.
• Fast-acting operation: Littelfuse identifies the JLLN225 with a Fast-Acting (F) opening characteristic.
• Current-limiting design: Provides another defined performance characteristic for matching the fuse to the intended electrical application.
• 300VAC maximum rating: Suitable for compatible AC equipment operating within the manufacturer's specified voltage limit.
• 125VDC maximum rating: Supports compatible DC applications within the specified voltage limit.
• Knife-blade/bolt-in format: Makes physical configuration an easy-to-identify checkpoint when confirming compatibility.
• Non-indicating: The JLLN225 is specified as a non-indicating fuse.

Material Compliance and Certifications

The supplied manufacturer specifications do not identify specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification information for the JLLN225. That does not mean the fuse lacks any particular certification or compliance status. When an approval or material requirement matters for the installation, confirm it with current, authoritative Littelfuse documentation and the product's markings rather than assuming certification based on the fuse class or series.

Where It Works Best

The Littelfuse JLLN225 225A Class T fuse is a logical fit for compatible electrical equipment that specifically requires a 225A, fast-acting, current-limiting Class T fuse with knife-blade/bolt-in construction. Its clearly stated AC and DC ratings also make compatibility checks easier: 300VAC maximum with 200 kA interrupting capacity at 300VAC, or 125VDC maximum with 20 kA interrupting capacity at 125VDC. The fuse block, clip, or holder arrangement must also suit the equipment.
