Eaton BK/SC-1/2 SC fuse - 100 kAIC at 600 Vac
Part Number: BK/SC-1/2
Quick Summary
Eaton BK/SC-1/2 SC fuse protects electrical circuits in panelboards and HVAC applications. Engineers often face nuisance trips and inconsistent protection, which this fast-acting, current-limiting device helps prevent while safeguarding downstream equipment. While RoHS compliant, the data sheet does not list CE, SIL, or IP certifications, but it carries the Class G fuse design and non-indicating operation that align with common panel protection standards. The compact form factor and bulk packaging simplify stocking and field replacement, delivering faster maintenance and reduced inventory costs for industrial facilities. This combination supports reliable, scalable protection across new equipment builds and retrofit projects.

Eaton Specification Sheet - BK/SC-1/2
Current-limiting, fast-acting protection is the core feature of the BK/SC-1/2, enabling rapid interruption of fault currents and minimizing energy released during a surge. By constraining let-through current, the fuse helps protect downstream devices, relays, and control electronics, reducing wear and extending component life. In panelboard and HVAC branch circuit protection, this combination supports safer startups, tighter coordination with upstream protective devices, and lower total cost of ownership through fewer nuisance trips and less downtime. Rejection-style construction ensures correct orientation during installation and prevents insertion into incompatible holders, reducing mis-wiring risks and simplifying inventory management. For maintenance teams, the result is faster replacements, fewer callbacks, and improved first-time fix rates in demanding environments like industrial plants and data centers. Class G construction with non-indicating operation minimizes panel clutter while enabling compact integration in tight spaces. The 600 Vac and 170 Vdc ratings, along with a 0.5 A current rating and 100 kAIC at 600 Vac (and 10 kAIC at 170 Vdc), provide flexible protection across mixed electrical systems, supporting cross-application deployment. Bulk packaging and a standard Bussmann catalog number, BK/SC-1/2, enable cost-efficient procurement and streamlined spares management, improving project timelines and reducing downtime in large facilities.

FAQs
BK/SC-1/2 is engineered to fit standard Bussmann SC fuse holders used in many electrical protection panels. Its 1.31 in length and 0.41 in cross-section align with common enclosure gaps, enabling straightforward replacement without modifications. For reliability, ensure the holder is rated for 600 Vac and 0.5 A, and verify upstream protection devices are coordinated to maintain selective tripping behavior during fault events.
Key specs include a 0.5 A amperage rating, 600 Vac voltage rating, 170 Vdc rating, 100 kAIC interrupt rating at 600 Vac, and 10 kAIC at 170 Vdc. The fuse is Class G and non-indicating, offering current-limiting protection with fast fault clearing to minimize downstream damage and downtime in panelboards and HVAC circuits.
Best suited for fusible branch panelboards and HVAC branch circuit protection, the BK/SC-1/2 provides rapid fault interruption that reduces arc energy and protects relays, control electronics, and downstream loads. Its bulk packaging and standard catalog inclusion also support OEM integrations and retrofit projects across industrial facilities.
The data indicates RoHS compliance, which supports environmental and regulatory expectations for many markets. The spec does not list CE, SIL, or IP certifications. If your project requires specific certifications, verify with Eaton’s datasheet or contact a representative to confirm current compliance and any regional variations.
Using this fuse reduces downtime through reliable, rapid fault clearing and improved upstream coordination. Bulk packaging lowers spares costs and simplifies procurement for large facilities, OEMs, and service teams. The non-indicating design reduces cosmetic maintenance, while consistent performance across AC and DC applications helps extend system uptime and reduce total cost of ownership.
