Eaton BK/SC-4 Fuse - 100 kAIC at 600 Vac
Part Number: BK/SC-4
Quick Summary
The Eaton Bussmann series SC fuse delivers fast-acting, current-limiting protection for HVAC branch circuits. Design engineers often wrestle with nuisance trips and choosing fuses that can handle peak fault currents without sacrificing time-to-protection. RoHS compliant is listed in the data, and while CE or SIL certifications aren’t specified, the device is rated for 600 Vac and 170 Vdc. With bulk packaging and a compact 1.31 in length footprint, it supports streamlined procurement and reliable panel protection. This combination helps equipment owners meet uptime targets and simplify maintenance planning. Industrial buyers value a fuse with a proven track record in panel protection and straightforward procurement in bulk.

Eaton Specification Sheet - BK/SC-4
Feature: Current-limiting fast-acting design minimizes fault energy, protecting downstream components and reducing arc flash potential. Business impact: Faster fault clearance translates to less heat and wear on motors, drives, and control wiring, shortening downtime and lowering repair costs. Application: Suited for HVAC branch circuits and fusible branch panelboards that demand reliable, rapid interruption without nuisance tripping.Feature: High interrupt rating supports rugged service in commercial environments. Business impact: With 100 kAIC at 600 Vac and 10 kAIC at 170 Vdc, the BK/SC-4 handles large fault currents from motors and compressors while keeping system voltage integrity. Application: Ideal for electrical protection schemes in air handling units and other HVAC equipment that require robust fault clearance.Feature: Voltage ratings and physical class. Business impact: 600 Vac / 170 Vdc ratings offer broad compatibility with mixed supply schemes, while the Class G, non-indicating design reduces panel clutter and simplifies replacement during maintenance. Application: Works well in standard bulk- packaged modules and field installations where quick swap is critical.Feature: Rejection style and packaging. Business impact: Rejection style helps ensure correct fuse orientation during panel assembly, reducing mis-wiring risk, and bulk packaging lowers procurement costs and inventory complexity. Application: Fit for bulk buys in manufacturing plants and service contractors stocking stair-step replacements.Feature: Compact form factor and compatibility. Business impact: With a length of 1.31 in, width 0.41 in, height 0.41 in, and weight 0.1 lb, this fuse slips into tight panel spaces without obstructing adjacent components, accelerating installation. Application: Suitable for standard Bussmann SC series panelboard configurations and new installations.Overall, the BK/SC-4 provides reliable, RoHS-compliant protection with bulk convenience and proven performance.

FAQs
BK/SC-4 is designed for use with Bussmann series SC panelboards and bulk-furnished HVAC protection schemes. Its 1.31 in length and 0.41 in width/height fit compact spaces, and the 600 Vac/170 Vdc ratings align with common commercial electrical distributions. When replacing, ensure correct rejection-style orientation and verify panel clearance to avoid interference with adjacent components.
BK/SC-4 is a 4 A fuse with 100 kAIC interrupt rating at 600 Vac and 10 kAIC at 170 Vdc. It carries a voltage rating of 600 Vac and 170 Vdc, is of Class G, non-indicating type, and ships in bulk packaging. These specs support reliable fault clearance for HVAC branch circuits while maintaining component protection boundaries.
This fuse is well-suited for HVAC applications, including air handling units and rooftop equipment, as well as other branch circuit protections in commercial buildings. The current-limiting, fast-acting behavior minimizes downstream damage, helps maintain uptime, and supports efficient maintenance with bulk procurement. Its small form factor aids retrofit into crowded panels.
The data confirms RoHS compliance. There is no explicit listing of CE or SIL certifications in the provided data. For applications requiring specific regulatory approvals, verify with Eaton’sdatasheets or contact a representative to confirm current certifications and qualifications for your region.
Bulk packaging reduces stocking frequency and part handling costs, supporting lower total cost of ownership. The 4 A, 600 Vac rating paired with a compact footprint simplifies ordering and installation in multiple HVAC installations. Maintenance teams benefit from consistent, quick replacements and predictable spare part usage.
