FCF_RN Finger-Safe Fast-Acting CUBEFuse

  
Finger-Safe Fast-Acting
CUBEFuse®
Delivers Superior
Protection with up to a 75%
Smaller Footprint

• Fast-acting protection specifically for UPS and other critical applications
• Finger-safe fuses minimize exposure to live parts, reducing hazard to personnel 
• Integral use with Compact Circuit Protector (CCP) or CUBEFuse holder minimizes panel space
• Minimizes incident energy and reduces arc-flash hazards utilizing Class J electrical characteristics
• Available in Cooper Bussmann Quik-Spec Coordination Panelboard for easy installation in the smallest fusible panel footprint

CUBEFuse Holders, Disconnects and Panelboards

The CUBEfuse is used in the following Cooper Bussmann products.


All 100, 60 and 30A CUBEFuse holders can be dovetail together for the required number of poles with the smallest Class J fuse footprint possible.

The DIN rail mounted 1-, 2-, and  3-pole CCP_CF comes in 30, 60 and 100A versions. The CCP_CF is a compact, horsepower rated disconnect that offers 3X the protection in 1/3 the space of traditional circuit breaker solutions. Local, neon open fuse indication is standard (same as the CCPB in the Quik-Spec™ Coordination Panelboard). 2- and 3-pole versions are ganged and all versions offer a lockout/tagout provision for added safety.

1-, 2-, and  3-pole CCPB is an an ampacity-rejecting branch disconnect for the Quik-Spec™ Coordination Panelboard that uses the CUBEFuse up to 100A.
