JLLS225 - 225Amp Fuse

JLLS225 - 225Amp Fuse

The JLLS225 is a 225-amp Class T fast-acting fuse for electrical systems that require high interrupting capacity in a compact, current-limiting design. Rated for up to 600VAC and 300VDC, it provides a 200 kA AC interrupting rating and a 20 kA DC interrupting rating at 300VDC. That makes it a straightforward choice when you're replacing an existing JLLS225 or working with equipment specifically designed for a 225A Class T fuse. Remember, amperage is only part of the equation—a proper replacement should also match the required voltage, fuse class, interrupting capacity, mounting configuration, and equipment specifications.

Key Features and Benefits

• 225A continuous current rating for circuits and equipment designed around a 225-amp fuse.
• Handles applications rated up to 600VAC or 300VDC.
• Fast-acting operation protects without an intentional time delay.
• Current-limiting Class T design helps reduce fault current that can pass through the circuit during qualifying overcurrent events.
• Compact knife-blade/bolt-in construction for use with the correct Class T mounting hardware.
• Non-indicating design for applications where a blown-fuse indicator is not required.
• Designed for mounting in a fuse block, clip, or holder.
• Specified for use with the LFT60400 Series holder.

Material Compliance and Certifications

The JLLS225 belongs to the JLLS family of Class T, current-limiting fuses. The product information supplied identifies its electrical class, construction, operating characteristic, and ratings. Still, it does not provide enough detail to substantiate specific material composition, RoHS status, or individual UL/CSA certification numbers for the JLLS225.

Where It Works Best

The JLLS225 225A Class T fuse is a strong fit for commercial and industrial electrical equipment specifically engineered for a 225A, fast-acting Class T fuse rated up to 600VAC. Its compact Class T format, current-limiting characteristics, and high AC interrupting capacity make it suitable for compatible power distribution equipment, disconnects, panels, and other electrical equipment that requires these exact fuse characteristics.
