KTU-1800 - 1800Amp Fuse

KTU-1800 - 1800Amp Fuse

When you replace a fuse, finding the right amperage is only one part of the puzzle. Take the Eaton Bussmann KTU-1800, for example. This heavy-duty 1800A Class L fuse is rated for 600V and delivers a remarkable interrupt rating of 200 kAIC at 600 Vac. For maintenance teams, electricians, and anyone sourcing electrical components, having these details on hand makes it much easier to compare the KTU-1800 with existing documentation or part numbers.

Key Features and Benefits

• 1800A amperage rating — Gives you a clear starting point for checking the fuse against the equipment's documented electrical requirements.
• 600V voltage rating — Another essential specification to verify before selecting a replacement.
• Class L classification — Helps identify the required fuse class rather than relying on amperage or catalog number alone.
• Bolted blade end x bolted blade end connection — Makes the physical connection configuration easy to compare with the existing installation.
• Ferrule design — Listed by the manufacturer as a special feature of the KTU-1800.
• Non-indicating configuration — The fuse indicator is listed as non-indicating.
• CE Marked and RoHS Compliant — Supplies documented compliance information for applications where these requirements need to be confirmed.

Material Compliance and Certifications

The KTU-1800 is RoHS Compliant and CE marked per the supplied manufacturer specifications. Its listed construction materials are silver-plated end bells and a melamine glass tube. Those details give buyers and maintenance personnel additional information to compare with equipment documentation, facility requirements, or an existing fuse before replacement.

Where It Works Best

The Eaton Bussmann KTU-1800 fuse is a candidate to compare against equipment specifications calling for a 1800A, 600V Class L fuse with a 200 kAIC at 600 Vac interrupt rating. When reviewing it for a replacement, don't stop at those electrical ratings. Also confirm the bolted blade-to-bolted blade connection, bolt mounting method, ferrule design, and physical dimensions.
