Eaton Specification Sheet - BK/BBS-3
Feature: 3 A amperage rating with a 10 kAIC interrupt rating at 600 V. Business Impact: Fast, reliable interruption minimizes fault energy and reduces downtime, protecting downstream equipment and improving uptime metrics. Application: Control circuits and instrumentation in electrical panels where compact, high-fault-current protection is required. Situation: Reduces arc energy and collateral damage in sensitive automation gear. Feature: Non-indicating fuse design. Business Impact: Simpler panel layouts and fewer visual indicators to monitor, lowering maintenance costs. Application: Bulk-installed devices in OEM assemblies where indicators are unnecessary. Situation: Streamlined procurement and installation without extra wiring or indicators. Feature: Material construction—fiber tube with nickel-plated brass endcaps. Business Impact: Enhanced ruggedness and vibration resistance for harsh industrial settings. Application: Enclosures subject to machine vibration and frequent handling. Situation: Longer service life and fewer replacement cycles. Feature: 600 V rating and 3 A rating. Business Impact: Compatible with mid-voltage control circuits and HID ballast protection, ensuring fast-acting fault clearance. Application: Automotive, manufacturing, and packaging lines using Bussmann series fuses. Situation: Consistent performance across standard Bussmann catalog products. Feature: Bulk packaging. Business Impact: Lower total cost of ownership through bulk procurement and inventory optimization. Application: OEM production lines and maintenance stocking for easy reorder. Situation: Reduces per-unit price and simplifies logistics. Feature: CE Marked and certified documentation. Business Impact: Streamlined regulatory compliance for European installations. Application: European facilities and multi-region deployments. Situation: Eases audit readiness and project approvals.

FAQs
BK/BBS-3 is designed for standard Bussmann-Series mounting footprints and control-panel assemblies. Its dimensions 1.9 in length, 2.9 in height, and 1.23 in width fit typical compact enclosures. When replacing existing fuses, verify identical amperage (3 A), voltage rating (600 V), and the same terminal style to ensure secure, code-compliant installation.
The 3 A rating defines the continuous operating current before trip, while 10 kAIC at 600 V is the maximum interrupt current the fuse can safely interrupt without damage. This combination affords fast fault clearance for control circuits and instrumentation, protecting sensitive devices and reducing the likelihood of cascading failures in medium-voltage control panels.
Yes. The BK/BBS-3 is well-suited for control circuits, HID ballast protection, and electronic circuits where quick interruption at up to 600 V is needed. Its bulk packaging supports bulk procurement for OEM and refurbishment projects, while its fast-acting characteristics help minimize damage in short-circuit events common in industrial automation.
The BK/BBS-3 is CE marked, confirming European compliance. For additional approvals, refer to the product's Certifications field and consult Eaton’s datasheets or contact the manufacturer. Keeping documentation up-to-date helps meet site-specific regulatory requirements and assists in passing audits in multi-region deployments.
Bulk packaging reduces per-unit cost and simplifies inventory management for high-volume projects. The BK/BBS-3’s compact size and bulk notes align with OEM stocking strategies, enabling faster turnarounds and lower warehousing costs. Long-term, this translates to lower total cost of ownership and improved project throughput.
