Bussmann series KTS-R 600 V Class RK1 fuse data sheet no. 1044
Feature: Fast-acting, current-limiting protection reduces fault energy and coordinates with upstream breakers. Business Impact: minimizes arc flash exposure, lowers equipment wear, and shortens downtime during faults. Application: ideal for motor control centers and panelboards in manufacturing lines where rapid fault clearance preserves downstream equipment and production continuity. Feature: High interrupt rating of 200 kAIC at 600 Vac. Business Impact: safely interrupts large fault currents without welding contacts, reducing damage and replacement costs. Application: feeders and drives in demanding industrial power systems where fault current levels can spike. Feature: Rejection-style knife blade design. Business Impact: reduces mis-insertion risk and ensures only compatible fuses are installed, improving field-service safety and reliability. Application: multi-supply environments and serviceable enclosures requiring straightforward installation checks. Feature: Compact physical footprint (7.88 in L × 1 in W × 1 in H) and light weight. Business Impact: enables denser panel layouts, shorter wiring runs, and easier handling during installation. Application: space-constrained switchgear or control panels in automated lines. Feature: CE Marking and RoHS considerations. Business Impact: supports global regulatory readiness and compliant sourcing for international facilities. Application: global manufacturing sites and supply chains seeking standard, easy-to-source protection devices.

FAQs
The KTS-R-75 is a Class RK1 fast-acting fuse designed for 600 Vac industrial circuits. It suits Bussmann-series protection schemes and is commonly installed in motor control centers, panelboards, and feeders. Its 7.88 inch length and 1 inch cross-section fit standard 1-inch DIN-rail or enclosure cutouts in compact digits.
Key ratings include 75 A continuous amperage, a 200 kAIC interrupt rating at 600 Vac, and a 600 V voltage rating. These specs ensure reliable fault interruption for medium-to-large loads and help protect upstream equipment from damage during short circuits.
Yes. The fuse is CE Marked, indicating EU safety compliance, and Eaton notes RoHS considerations through official documentation and tools. This supports global deployments and regulatory readiness for international projects.
The KTS-R-75 measures 7.88 inches in length with a 1 inch width and a height of 1 inch, and it weighs about 0.5 pounds. These compact dimensions facilitate denser panel layouts, shorter wiring runs, and easier handling during installation.
The rejection-style knife blade design prevents incorrect insertion and ensures compatibility with only the intended fuse type. This improves maintenance safety, reduces mis-wiring risks, and aligns with Bussmann-series mounting practices for reliable, repeatable protection in demanding industrial environments.
