KLU-4000 - 4000Amp Fuse

KLU-4000 - 4000Amp Fuse

When you're dealing with 4000 amps, choosing the catalog number alone isn't enough. The KLU-4000 is a Class L fuse rated for 4000A at 600V, with a 200 kAIC interrupt rating at 600VAC and a quick 5-second response time at 500%. It features bolted blade connections and requires bolt mounting.

Key Features and Benefits

• 4000A current rating for equipment specifically requiring this Class L amperage.
• Rated for 600V operation according to the supplied manufacturer specifications.
• Classified as a Class L fuse, helping identify the required fuse format beyond current and voltage ratings.
• Manufacturer specifies a 5-second response time at 500% of rated current.
• The bolted blade-to-bolted blade connection defines the required physical connection arrangement.
• Uses a bolt mounting method for installation.
• RoHS compliant according to the supplied product data.
• CE marked, providing additional documented compliance.

Material Compliance and Certifications

The manufacturer information supplied for the KLU-4000 specifically identifies the product as RoHS compliant and CE marked. Those are the compliance details confirmed by the provided product data.

Where It Works Best

The KLU-4000 suits electrical equipment designed to accept a 4000A, 600V Class L fuse with a 200 kAIC interrupt rating at 600VAC and the manufacturer's stated 5-second response time at 500%.

Mechanical compatibility matters as much. The equipment should be designed for the KLU-4000's bolted blade-end connections, bolt mounting, 10.75-inch length/depth, 5-inch height, and 5-inch width. Because the supplied specifications disagree about whether this particular fuse is indicating or non-indicating, confirm that characteristic when it matters for the installation.
