Time-delay CUBEFuse up to 400 amps

Finger-safe, Class J electrical performance requires up to 70% less space

The finger-safe UL Class CF CUBEFuse and holder system provides a package that's the smallest footprint of any class fuse including Class J, CC, T and RK to provide substantial space savings and installation flexibility.

IEC 60529 and finger-safe rating provides enhanced workplace safety.

Separate overload and short-circuit elements provide time delay for sizing of high inrush loads linked with Class J current limitation.

Selective coordination ratio of 2:1 (within Low-Peak fuse family) prevents electrical shut downs from extending beyond the failed circuit.

Typical applications:

  • Electrical panelboards
  • Machinery disconnects
  • Industrial controls and panels
  • Required finger-safe systems
