Eaton BK/SC-30 Fuse - 30 A Class G Rejection Style
Part Number: BK/SC-30
Quick Summary
The Eaton BK/SC-30 fuse is a current-limiting time-delay device ideal for protecting industrial power circuits. It helps prevent nuisance trips and minimizes downtime for motor drives, feeders, and critical power rails. The data notes RoHS compliance, and there are no SIL, CE, or IP certifications listed. Designed for compatibility with Bussmann series components, it uses ferrule-end terminations for quick, secure installation. Bulk packaging and a compact footprint simplify stocking and panel mounting, delivering dependable electrical protection in spaces with limited clearance. This combination supports reliable protection, simplified procurement, and streamlined maintenance in industrial automation environments.

Eaton Specification Sheet - BK/SC-30
Feature: Current-limiting time-delay fuse. Business Impact: Reduces energy let-through during faults and enables selective protection to minimize collateral damage. Application: Ideal for motor drives, feeders, and power distribution panels where uptime matters. The BK/SC-30 delivers controlled fault response without sacrificing speed, enabling safer start-ups and reduced component wear. Feature: 30 A amperage rating with 12 seconds at 200% overload. Business Impact: Predictable coordination with upstream protections, lowering the risk of nuisance shutdowns in transient-heavy loads. Application: Panel boards and control feeders in automation lines benefit from consistent performance during startup surges. Feature: High interrupt ratings—10 kAIC at 300 Vdc and 100 kAIC at 480 Vac. Business Impact: Enhanced fault tolerance, protecting downstream devices and reducing fire and arc-flash risk. Application: Industrial AC networks and DC control circuits operating at 480 Vac and 300 Vdc gain strong protection margins. Feature: Ferrule end x ferrule end with rejection-style design. Business Impact: Faster, more reliable field maintenance with correct fuse-path alignment; minimizes cross-compatibility errors. Application: Quick replacements in control panels and fuse blocks, backed by standard Bussmann interfaces. Feature: Bulk packaging and compact footprint (0.41 in x 1.62 in x 0.41 in, 0.18 lb). Business Impact: Lower unit costs, easier inventory management, and simpler shipping to OEMs and service teams. Application: High-volume procurement for manufacturers and service fleets reduces logistics overhead.

FAQs
BK/SC-30 uses ferrule-end terminals that fit standard Bussmann fuse blocks and panels. Ensure the host holder supports Class G current-limiting fuses and the device ratings of 480 Vac / 300 Vdc. Follow manufacturer torque specifications and verify secure ferrule connections to maintain vibration resistance in industrial environments.
12 seconds at 200% indicates the fuse will open within about twelve seconds when the circuit current is twice the 30 A rating. This enables selective coordination with upstream protection, allowing normal operation during moderate overloads while providing rapid fault clearance during sustained faults, reducing equipment damage.
Yes. BK/SC-30 is rated for 480 Vac and 300 Vdc with a 10 kAIC interrupt rating at 300 Vdc. It is suitable for DC control circuits within that rating, provided the system coordination and fault current align with the fuse’s characteristics and the rest of the protection scheme.
The available data notes RoHS compliance but does not list CE marking or IP ratings. If CE or IP certifications are required for your application, confirm with Eaton or select a fuse that explicitly carries those certifications to ensure regulatory compliance.
Bulk packaging reduces per-unit costs and simplifies stocking for OEMs and service teams, lowering logistics and warehousing expenses. The compact size and non-indicating design streamline installation and replacement, improving mean time between replacements and overall maintenance efficiency in industrial protection schemes.
