Dual-element current-limiting CUBEFuse design features fast fault clearance, protecting downstream components and reducing arc energy. This translates into lower insulation stress, fewer damaged feeders, and shorter downtime in automated lines. Use it in motor control centers, panel feeders, and critical automation cabinets where reliable protection is essential. Class CF construction with fast-acting protection and a 30 kA interrupting rating at 690 Vac enables selective coordination with upstream breakers, improving safety and reducing replacement costs in high-energy environments. Finger-safe, non-indicating design simplifies maintenance in crowded panels, while the compact cube form factor (3.01 in L Ă— 1 in W Ă— 1.26 in H) aligns with standard Bussmann WCF enclosures for quick swaps and straightforward stocking. Compatibility with the Eaton Bussmann series reduces procurement time and ensures consistent performance across spares. Documentation, catalogs, and data sheets support fast engineering sign-off and compliant installations.
