FAQs
Install the blade-end fuse into a matching blade terminal holder designed for Class CF cube fuses. Verify the fuse length of 3.01 in and width of 1 in, ensure proper alignment with terminals, and secure with the panel’s standard mounting hardware. Confirm ambient temperature within -40 to 80°C and check that the holder supports 100 A rating to avoid overheating or premature failure.
The FCF100RN provides a 100 A amperage rating, a voltage rating of 600 Vac and 600 Vdc, and interrupt ratings of 200 kAIC at 600 Vac and 50 kAIC at 600 Vdc. It offers a response time of 8 minutes at 200% overload conditions, supporting predictable protection for critical loads in automation systems.
Yes. The fuse is designed for control panels and motor drive protection, with a Class CF fast-acting profile, a wide operating temperature range, and compatibility with standard Eaton holders. It is UL Listed, CSA Certified, CE RoHS compliant, and rated for 50–60 Hz operation, making it suitable for diverse industrial applications.
The FCF100RN is UL Listed, CSA Certified, and CE Marked RoHS Compliant, providing safety validation and regulatory alignment for global installations and procurement programs.
As a fast-acting cube fuse, plan for periodic inspection in high-demand lines and prepare replacement spares to minimize downtime. The fuse is non-indicating, so incorporate routine electrical testing and panel diagnostics to confirm continued protection, and ensure compatibility with existing holders to avoid contact resistance or misfit during swaps.
