Eaton Specification Sheet - BK/JJS-30
Feature — Current-limiting, very fast-acting design. This fast response clamps fault current quickly, protecting upstream gear and reducing energy released during a fault. Application areas include VFD line protection, multi-family meter stacks, and other commercial installation scenarios where rapid isolation is critical. Business Impact — Reduces downstream damage, lowers maintenance costs, and tightens protection coordination with downstream breakers. Application — ideal for VFD line protection, feeder protection in large apartment complexes, and multi-family meter stacks in commercial buildings. Feature — Compact footprint and slim profile (1.5 in length, 0.56 in width and height). Business Impact — enables higher packing density in control panels, simplifies retrofits, and reduces enclosure depth requirements. Application — easy fitting into crowded electrical rooms and retrofit projects where space is at a premium. Feature — 30 A rating with a 200 kAIC interrupt rating at 600 Vac. This combination delivers robust fault current handling and improves coordination with upstream protective devices. Application — mains feeders and branch protection for 600 V systems in commercial and residential multi-family infrastructure. Feature — Class T construction with non-indicating, rejection-style features. Business Impact — enhances protection selectivity while preventing misplacement in assemblies, and simplifies inventory by aligning with standard Bussmann series components. Application — widely compatible with 600 V Class T fuses in Eaton Bussmann line and standard bulk SKUs. Feature — Compliance and procurement advantages: CE Marked and RoHS compliant, bulk packaging, and a standard 600 V rating. Business Impact — supports regulatory compliance, streamlined purchasing, and faster stocking for maintenance teams. Application — suitable for global installations and bulk procurement programs in property management and electrical contracting.

FAQs
BK/JJS-30 is a 30 A current-limiting, very fast-acting fuse with a 200 kAIC interrupt rating at 600 Vac and a 600 V voltage rating. It uses Class T construction and a non-indicating design, suitable for 600 V distribution in VFD lines and feeder protection. It’s compatible with Eaton Bussmann JJS family and is ideal where fast fault clearing and high fault current withstand are required.
Install BK/JJS-30 primarily in large apartment complexes, multi-family meter stacks, and commercial buildings where VFD line protection and main feeders need compact, reliable protection. Its bulk packaging and small footprint simplify stocking and retrofits, reducing downtime during maintenance windows. It also supports utility-grade protection in 600 V distribution schemes.
The fuse has a compact footprint (1.5 in length, 0.56 in width and height), which fits tight panel layouts. Use standard Bussmann series compatible holders and bulk packaging to simplify stocking. The non-indicating indicator design means routine visual checks are minimized; plan for electrical protection logic accordingly.
BK/JJS-30 meets CE marking and RoHS compliance, aligning with European and global safety standards. These certifications support regulatory acceptance and sustainability goals for 600 V distribution networks. The device is commonly used in bulk procurement programs; always verify local codes and utility requirements for your project.
Using BK/JJS-30 improves uptime by delivering rapid fault isolation, reduces repair costs through minimized fault energy, and simplifies procurement with bulk packaging and standard Bussmann series compatibility. For building managers and electrical contractors, this translates to faster service restoration, predictable maintenance budgets, and streamlined stocking in large-scale projects.
