Bussmann series Wind CUBEFuse data sheet no. 9009
Feature: Dual-element current-limiting CUBEFuse design. Business Impact: Provides fast fault isolation while minimizing let-through energy, reducing arc flash risk and equipment damage. Application: Control panels and machine safety circuits benefit from tighter short-circuit control without compromising uptime. Feature: 80 A amperage rating. Business Impact: Protects downstream equipment from overcurrent while enabling compact protection schemes, lowering upstream conductor sizing and improving overall system reliability. Application: feeders and motor control circuits in manufacturing lines. Feature: Interruption rating of 30 kA at 690 VAC. Business Impact: High fault-current events are cleared quickly, protecting busbars and cabinets and meeting stringent industrial protection requirements. Application: power distribution blocks in harsh industrial environments. Feature: Finger-safe, non-indicating design (Class CF). Business Impact: Safer handling during maintenance and replacement with reduced need for contact protection, while avoiding nuisance trips tied to indicator fuses. Application: OEM equipment and field-replaceable fuses in enclosed panels. Feature: Glass-filled PES body, 3.01 in L × 1.26 in H × 1 in W. Business Impact: Compact footprint simplifies installation in crowded panels and standard Bussmann series enclosures, reducing mounting space and improving serviceability. Application: space-constrained control cabinets and electrical housings. Feature: RoHS compliant and CE marked. Business Impact: Ensures global compliance for export and installation in regulated markets, easing procurement and integration across multinational facilities. Application: international manufacturing and distribution networks, cross-border projects.

FAQs
The WCF80RN uses the standard CUBEFuse form factor within Bussmann series assemblies, offering a compact 3.01 in length, 1.26 in height, and 1 in width. It is designed for finger-safe handling and fits typical low‑voltage branch circuit enclosures, enabling straightforward retrofits and OEM implementations without special tooling.
The fuse provides an 80 A amperage rating with a 30 kA interrupting rating at 690 VAC. This combination means it can safely interrupt high fault currents in industrial power circuits, while protecting conductors and equipment from overcurrent conditions in control panels and distribution boards.
Yes, the WCF80RN is RoHS compliant and CE marked. This ensures the device meets European environmental and safety standards, facilitating international procurement, harmonized integration into global product lines, and compliance with regulatory requirements in most export markets.
This Class CF dual-element fuse is ideal for machine control panels, drives, and power distribution in manufacturing and processing environments. Its non-indicating design means you cannot rely on a visual trip indicator; plan for external status monitoring or replacement scheduling to manage fault events reliably.
Because the WCF80RN is non-indicating, routine maintenance should include periodic inspection of enclosure integrity and external fault indicators in the control system. Standard replacement practices apply, and its finger-safe construction reduces handling risk during routine service while maintaining quick swap-out capabilities in repair workflows.
