Eaton Bussman Fast-acting CUBEFuse™

February 2, 2025

Eaton’s Bussmann™ series fast-acting CUBEFuse™ delivers a faster response to damaging faults to help reduce destructive thermal and magnetic forces. It is ideally suited for UPS and other critical applications.

The industry’s first fingersafe CUBEFuse is a Class CF fuse that provides the same electrical performance as a Class J fuse, but with a significantly smaller footprint.

Features and benefits:

  • Fast-acting protection specifically for UPS and other critical applications.
  • Finger-safe fuse minimizes exposure to live parts, reducing the likelihood of accidental contact with energized parts.
  • Integral use with Compact Circuit Protector (cat. no. CCP2) or CUBEFuse holder to minimize panel space.
  • Minimizes incident energy and reduces arc flash hazards utilizing Class J current-limiting electrical characteristics.
  • Smallest footprint of any class fuse including Class CC, J, RK and T.
