Bussmann FCF50RN – Frequently Asked Questions

1) What fuse holder does the Bussmann FCF50RN fit?
The FCF50RN is a Class CF fuse with blade ends, and it's specified for use with the Bussmann TCFH60N fuse holder and the CCP2-3-60CF compact circuit protector. Class CF is a dedicated form factor, so it does not drop into a standard Class J, CC or R clip or block.
2) Can I use the FCF50RN on a 600 volt DC circuit, or is it AC only?
Both. It carries a 600 Vac and 600 Vdc rating, with 300 kAIC interrupting at 600 Vac. On AC it works on 50 Hz and 60 Hz systems, so it's fine for either domestic or export panel work.
3) Will this 50 amp Bussmann CF fuse hold motor inrush without nuisance blowing?
It's a time-delay characteristic: 6 minutes minimum at 200% of rating. At 50 A that means it rides through a sustained 100 A overload for several minutes, which covers motor starting current and transformer inrush. Single element construction.
4) Is the Bussmann FCF50RN finger safe for live panel work?
Yes. The FCF50RN has a finger safe body, molded from glass filled PES with electroless tin plated copper alloy blade terminals. That construction is what lets it be handled in an energized enclosure without exposed metal, which is the main reason spec writers call out Class CF over open-clip fuse types.
5) Does this fuse have a blown fuse indicator?
No. The FCF50RN is the non-indicating version, so there's no visual flag or pin to show it has opened. If your maintenance crew relies on a pop-up indicator to find the open leg, order the indicating variant of the FCF series instead.
6) Will the FCF50RN hold up in an unheated outdoor or rooftop enclosure?
Its operating temperature range is -40 to 80 degrees C, which covers cold climate exterior cabinets and hot rooftop equipment. It's UL Listed and CE Marked.
7) Is a 300 kAIC fuse overkill for my service, or do I need it?
The 300 kAIC rating at 600 Vac is the available fault current the FCF50RN can safely clear. You need a device rated at or above the short circuit current available at that point in the system. On a large service or close to a big transformer, that number matters; on a small branch it simply means you are covered.
8) What exact part do I order to replace a blown FCF50RN?
Order Bussmann part number FCF50RN. It's the black, 50 A, 600 V, non-indicating Class CF fuse. Amp rating, class and indicating style all have to match what came out, since CF holders accept a range of amperages within the same physical size.
