FAQs
For the BBS-1-1/2, verify that the ferrule-end terminations match the fuse ends and use compatible ferrules for secure seating. Tighten endcaps per recommended torque and avoid cross-threading. Since this model is non-indicating, confirm status with a test instrument during commissioning. The compact 0.36 in square profile helps fit crowded panels while maintaining insulation clearance.
The fuse has a 10 kAIC interrupt rating at 600 Vac, providing robust fault current handling in industrial power circuits. In a fault, it clears quickly to protect upstream equipment, while maintaining selectivity with other protection devices and predictable clearing times for reliable system uptime.
Yes, the BBS-1-1/2 is designed as a replacement for F20B fuses, offering backward compatibility with existing Bussmann series installations. This helps reduce spare-part inventory and simplifies migration across legacy systems without changing wiring or end-cap configurations.
The BBS-1-1/2 carries CE Marking, indicating compliance with European safety requirements. While other region-specific certifications vary by application, CE marking supports regulatory alignment for European projects and standard procurement practices globally where CE is recognized.
Adopting the BBS-1-1/2 contributes to higher uptime, predictable protection, and lower maintenance costs. The 1.5 A rating protects sensitive control circuits, while the 10 kAIC rating supports fault resilience. Nickel-plated endcaps and silver-plated caps improve longevity in dirty or humid spaces, reducing replacement cycles and stocking complexity.
