KLU-2500 - 2500Amp Fuse

KLU-2500 - 2500Amp Fuse

At 2500 amps, the KLU-2500 is a very specific Class L fuse, and getting the replacement right means checking more than amperage. The KLU-2500 is rated 600V with a manufacturer-specified 200 kAIC interrupt rating at 600VAC and a 5-second response time at 500% of rated current. Whether you're checking an existing fuse or confirming a replacement against equipment documentation, compare the full set of electrical and mechanical specifications rather than relying on the 2500A rating by itself.

Key Features and Benefits

• 2500A amperage rating for equipment designed to use a Class L fuse at this current rating.
• Rated at 600V, a key specification to compare with equipment requirements.
• Class L designation makes fuse-class verification straightforward when checking compatibility.
• Manufacturer specifies a 5-second response time at 500% of rated current.
• The bolted blade-end-to-bolted blade-end connection provides a clearly defined mechanical configuration.
• Uses a bolt mounting method rather than a clip-mounted cartridge arrangement.
• Non-indicating fuse design, as confirmed by both the fuse-indicator and special-features fields in the supplied data.
• RoHS compliant according to the supplied manufacturer information.
• CE marked for an additional documented compliance characteristic.

Material Compliance and Certifications

The supplied manufacturer specifications identify the KLU-2500 as RoHS-compliant and CE-marked. Those are the specific compliance characteristics documented for this catalog number in the information provided.

Where It Works Best

The KLU-2500 suits electrical equipment designed for a 2500A Class L fuse rated 600V, with a 200 kAIC interrupt rating at 600VAC and the manufacturer's specified 5-second response time at 500%.

Mechanical compatibility deserves equal attention. The installation needs to accommodate bolted blade ends on both sides, bolt mounting, and the KLU-2500's 5-inch length/depth, 5-inch width, and 1.75-inch height. Because this model is explicitly specified as non-indicating, that characteristic should also match the intended installation requirements.
