Wind CUBEFuse
™
For Wind Power Generation Applications
Features and Product Benefits
• Maximize uptime and reliability using fuses designed and
recognized to UL 248 for low voltage fuses
• Fast-acting protection specifically designed for low-fault
current conditions that occur in wind power generation
systems
• Minimize chances of equipment failure and personnel injury
when using full range fuses having fast response time to
low-magnitude faults
• Simplify compatibility with readily available industry
standard Class CF holders while minimizing panel space by
up to 80%
• Meets all UL specified overload opening requirements
• Minimizes incident energy and reduces arc flash hazards
utilizing Class J electrical characteristics
• Finger-safe feature minimizes exposure to live parts,
reducing hazard to personnel
Catalog Symbol:
