Bussmann series UL Class CF CUBEFuse data sheet no. 9000
Class CF time-delay, dual-element cube fuse provides selective protection for fast faults while tolerating motor inrush. This design reduces nuisance trips and extends equipment lifespan by avoiding unnecessary disconnections during startup surges. It is well suited for motor drives, power distribution blocks, and control panels where reliable, predictable protection is essential. The 100 A rating and wide voltage handling enable use across both 600 Vac and 300 Vdc systems, simplifying spec alignment for mixed-voltage installations and reducing component count. With a blade-end connection and 35 mm DIN rail mounting, installation is straightforward, enabling faster panel builds and easier field replacements. The finger-safe enclosure and with-indicator fuse option further enhance safe maintenance and quick fault identification in busy industrial environments. Compatible with TCFH100N and CCP2-3-100CF devices, the TCF100 integrates cleanly into existing Bussmann series architectures, improving spare parts commonality and total cost of ownership. Compliance certifications like UL Listed and CSA Certified support regulatory acceptance across target markets, while RoHS reduces hazardous material concerns for modern assemblies.

FAQs
Plan for a standard 35 mm DIN rail mount and use the blade end connection for quick insertion into right sized panels. Ensure the enclosure provides adequate clearance for the finger-safe design and allows visibility of the fuse indicator. Verify busbar or terminal alignment and torque specifications per the Bussmann data to prevent arcing or loose connections.
The TCF100 is rated for 100 A and supports 600 Vac and 300 Vdc. It provides 100 kAIC at 300 Vdc and 300 kAIC at 600 Vac, with a response time of 10 seconds at 500 percent overload. These ratings enable protection across mixed voltage systems while maintaining fast fault isolation to protect downstream equipment.
Yes, the TCF100 is suitable for motor protection in panel boards and MCCs. The time-delay characteristic accommodates motor inrush currents without nuisance tripping, while the dual-element design still provides current-limiting protection once the fault is detected, reducing downtime and improving motor longevity in startup-heavy applications.
The TCF100 carries UL Listed and CSA Certified marks, along with CE and RoHS compliance. These certifications support conforming to safety, electrical, and environmental requirements across regions, simplifying procurement for regulated industries and helping ensure product acceptance in global projects.
Common challenges include space constraints, inrush handling, and mixed voltage environments. The TCF100’s DIN rail mounting and blade-end connection save space and enable rapid swaps, while its 600 Vac / 300 Vdc ratings and current-limiting design help manage inrush and protect multiple subsystems without compromising safety or uptime.
