Bussmann KTU-600 LIMITRON Fast-Acting Fuse, 600A, 600V

The Bussmann KTU-600 is an Eaton Bussmann series KTU fuse featuring the LIMITRON fast-acting design, built to deliver dependable overcurrent protection in demanding electrical systems. Rated 600 A and 600 V, this non-indicating, standard-type fuse is engineered for a fast response to short-circuit and overload conditions, helping safeguard conductors, equipment, and connected loads from damaging fault currents. As part of the trusted Eaton Bussmann KTU lineup, the KTU-600 is a direct fit for applications that call for a 600 A, 600 V LIMITRON fast-acting fuse, and it is commonly specified as a like-for-like replacement in existing KTU-rated fuse holders and disconnects.

Key Features

  • Amperage Rating: 600 A, sized for high-capacity feeder and branch circuit protection in commercial and industrial power distribution.
  • Voltage Rating: 600 V, suitable for demanding industrial and commercial power distribution systems where higher-voltage overcurrent protection is required.
  • LIMITRON Fast-Acting Design: Delivers a rapid response to short-circuit and overcurrent events, helping limit let-through energy and protect downstream equipment.
  • Non-Indicating Construction: Standard non-indicating fuse body for straightforward overcurrent protection without a built-in blown-fuse indicator.
  • Standard Type: Configured as a standard fuse within the Eaton Bussmann KTU series for consistent, code-compliant performance across matching installations.
  • Eaton Bussmann Series KTU: Manufactured under the Eaton Bussmann KTU designation, making it straightforward to identify, cross-reference, and replace in existing systems.
  • Fast-Acting Overcurrent Response: The LIMITRON fast-acting characteristic is intended for circuits where a quick clearing time is the priority, rather than a time-delay response.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Overcurrent Protection in Electrical Distribution Panels
  • Motor and Equipment Short-Circuit Protection
  • Industrial and Commercial Power Distribution Systems
  • Panelboard and Switchboard Fuse Protection

Bussmann KTU-600 – Frequently Asked Questions

1) Can I use a Bussmann KTU-600 to replace a time-delay 600A fuse in a motor circuit?
No, not directly. The KTU-600 is a LIMITRON fast-acting fuse, built to clear quickly on short circuit and overload rather than ride through an inrush. Swapping it in where a time-delay fuse was sized for motor starting current will usually open the fuse on startup. Use the KTU-600 where fast clearing is the priority, such as short-circuit protection of equipment and feeders, and keep a time-delay class fuse where motor inrush has to be tolerated.
2) Is the Bussmann KTU-600 rated for a 480V three-phase industrial panel?
Yes. The KTU-600 carries a 600 V rating, so it covers 480 V and 600 V AC distribution systems as well as lower voltages. Its current rating is 600 A, sized for feeder and larger branch circuit protection in commercial and industrial panelboards and switchboards.
3) Will the KTU-600 drop into my existing KTU fuse clips without modifying the disconnect?
Yes, where the equipment was built for a 600 A, 600 V KTU fuse. The KTU-600 is the Eaton Bussmann series KTU part at that rating and is commonly specified as a like-for-like replacement in existing KTU-rated fuse holders and disconnects. Order it by the manufacturer part number KTU-600 and match the 600 A/600 V rating marked on the switch label.
4) What are the physical dimensions and weight of the KTU-600 fuse?
The KTU-600 measures 8.63 by 2.5 by 2.5 inches and weighs 3.75 lb. That body size matters when you are checking clearance inside a fused disconnect or switchboard compartment, and the weight is worth knowing if you are stocking several on a shelf or handling one overhead.
5) Does the KTU-600 have a blown fuse indicator?
No. The KTU-600 is a non-indicating fuse, so there is no pop-up pin or window to show it has opened. Maintenance crews will need to test continuity or use a voltage check across the fuse to confirm whether it has cleared. If your facility standardizes on visual blown-fuse indication for faster troubleshooting, specify an indicating version instead.
6) How do I order the Bussmann KTU-600 and how does it come packaged?
Order it by manufacturer part number KTU-600 under the Eaton Bussmann brand. It ships in standard packaging, not a bulk or specialty pack, so it is straightforward to carry as a shelf spare for any switchgear using 600 A KTU fuses.
7) What is the KTU-600 typically used for in a commercial building?
It covers overcurrent protection in distribution panels, panelboard and switchboard fuse positions, equipment short-circuit protection, and feeder or branch circuits running at 600 A. In practice it is most often bought as the replacement fuse for Eaton Bussmann KTU-rated gear already in a plant or building service.
