Eaton Specification Sheet - BK/SC-35
Current-limiting time-delay fuse reduces fault energy and protects wiring, contacts, and downstream electronics, enabling safer start-up sequences and coordinated protection in automation panels. The 35 A rating aligns with common control circuits, delivering predictable performance and minimizing downtime due to nuisance trips. Rejection-style design prevents incorrect installation, reducing commissioning time and safety risks during panel assembly. The device is rated for both 480 VAC and 300 VDC systems, ensuring compatibility across mixed AC/DC rack configurations and simplifying spare-part inventories for panel builders. Its 10 kAIC at 300 Vdc and 100 kAIC at 480 VAC fault-current ratings provide robust protection in high-short-circuit environments, improving equipment longevity and overall plant reliability. Class G designation and bulk packaging support standardized maintenance practices and scalable stocking for large projects, while RoHS compliance ensures regulatory alignment in modern manufacturing. These attributes collectively deliver measurable outcomes in efficiency, safety, and total cost of ownership for industrial controls and power distribution.

FAQs
Install BK/SC-35 into a compatible Bussmann SC fuse holder using proper torque on the terminal connections and ensuring alignment with the rejection-style design to prevent misinsertion. Verify voltage rating and amperage match your circuit and confirm that the panel is de-energized before replacement. The bulk packaging aids stock management for panel builders and installers working on large installations.
BK/SC-35 is a 35 A, current-limiting time-delay fuse with voltage ratings of 480 VAC and 300 VDC. It provides 10 kAIC at 300 Vdc and 100 kAIC at 480 VAC, and a response time of 12 seconds at 200%. These specs support protection of HV branch circuits in industrial automation and control cabinets, while enabling effective coordination with upstream protective devices.
Yes, the BK/SC-35 is RoHS compliant, aligning with modern regulatory expectations for restricted hazardous substances. It is designed as a Class G Bussmann SC fuse, intended for bulk distribution and panel integration in regulated industrial environments, helping maintain compliance without sacrificing protection performance.
This fuse is ideal for HV branch circuit protection in industrial control panels, power distribution centers, and automation cabinets. The rejection-style feature minimizes installation errors, while the 480 VAC / 300 VDC ratings support mixed AC/DC systems common in manufacturing floors, packaging lines, and machine control applications.
BK/SC-35 is sold in bulk and designed to slot into standard Bussmann SC fuse holders, aiding consistent stocking and quick swaps. While warranty is listed as Not Applicable, the device is compatible with other SC class fuses in common panel designs, enabling streamlined maintenance programs and optimized spare-part inventories in large facilities.
