FAQs
The 1BS102 uses screw connections with a stud-mounted base, supporting #6-250 kcmil Cu/Al conductors in 600 V systems. Follow Eaton torque specs for fasteners, ensure clean terminations, and maintain proper strain relief. This approach minimizes contact resistance and reduces hotspot risk, delivering reliable long-term performance in industrial environments.
The 1BS102 provides a 400 A amperage rating, a 600 V voltage rating, and a 200 kAIC interrupt rating. It is designed for use with Type SC fuses and features tin-plated aluminum connectors with zinc-plated steel studs to ensure durable, high-current protection in demanding panel assemblies.
Ideal for panel boards, motor control centers, and feeders in industrial environments, the 1BS102 supports Type SC fuses and large conductor sizes (#6-250 kcmil Cu/Al). It is well suited for high-current distribution needs where reliable fault protection and easy maintenance are priorities.
The 1BS102 is RoHS compliant per factory specification. For broader regulatory certifications beyond RoHS, consult Eaton to confirm current CE or other listings. This, combined with its 600 V rating and 200 kAIC interrupt capability, supports compliance in many global industrial environments.
Ensure tight, clean terminations with correct torque per guidance, use the recommended #6-250 kcmil conductors, and keep Type SC fuses properly seated. The combination of robust materials, modular design, and compatibility with Type SC fuses reduces spare parts, minimizes downtime, and extends service life in high-demand production lines.
