Eaton BK/SC-25 fuse - RoHS Compliant
Part Number: BK/SC-25
Quick Summary
The Eaton BK/SC-25 fuse provides 25 A current-limiting protection for industrial control circuits in panels and drives. Engineers often wrestle with nuisance trips and slow fault isolation; this fuse delivers predictable clearing with a defined time-delay. RoHS compliant and designed as a Class G, rejection-style device, it helps ensure regulatory alignment and selective protection in compact control panels. The ferrule-end connections simplify installation and reduce wiring errors, while the 12-second response at 200% overload and high interrupt ratings support uptime in motor drives and power distribution. Bulk packaging enables efficient procurement for OEMs and service teams, delivering consistent performance with minimal maintenance.

Eaton Specification Sheet - BK/SC-25
Feature → Business Impact → Application. The BK/SC-25 offers a 25 A current rating and current-limiting behavior that minimizes fault energy, protecting upstream devices and downstream loads in control panels and motor drives. This time-delay characteristic reduces nuisance trips during normal inrush events, increasing equipment uptime and allowing selective coordination across power circuits in industrial automation environments. With 10 kAIC at 300 Vdc and 100 kAIC at 480 Vac, the fuse provides robust fault-clearing capability for DC bus and AC mains sections, reducing the risk of cascading failures in critical machinery. The Class G construction, ferrule-end connections, and rejection-style design streamline installation, improving field reliability and preventing incorrect fusing during maintenance. RoHS compliance and bulk packaging address regulatory requirements and procurement efficiency, enabling consistent component quality across large projects.

FAQs
BK/SC-25 uses ferrule-end connections and a compact footprint (0.41 in x 0.41 in base with 1.62 in height), designed for standard bulk packaging. The rejection-style design helps prevent incorrect replacement, while its non-indicating indicator reduces field wiring clutter. For reliable mounting, ensure ferrule terminals align with panel wiring harnesses and that the bulk packaging is maintained to preserve part integrity.
The fuse is rated at 25 A with voltage ratings of 480 Vac and 300 Vdc. It provides 10 kAIC interrupt capability at 300 Vdc and 100 kAIC at 480 Vac, plus a 12-second response time at 200% overload. It’s a Class G, time-delay, current-limiting device with ferrule-end connections suitable for industrial protection schemes.
Yes, the BK/SC-25 is RoHS compliant, aligning with environmental and safety regulatory expectations. While the data here doesn’t list CE or IP ratings, RoHS compliance supports material and process standards typically required in modern electrical assemblies and OEM procurement.
Ideal for control panels, motor drives, and power distribution blocks where selective protection and fast fault clearing are essential. The 25 A rating with high interrupt capability makes it suitable for protecting downstream electronics and motors from overcurrent events, while the time-delay helps accommodate normal inrush without compromising protection.
Procurement benefits from bulk packaging that supports scalable replacement in larger installations. The ferrule-end design and rejection-style construction minimize installation errors, while the RoHS compliance ensures regulatory compatibility across regions. With non-indicating status, routine visual checks are recommended during scheduled maintenance to confirm fuse status after faults.
