Frequently Asked Questions

What is included in this FNQ-1-1/8 listing?
The listing contains 10 individual Bussmann FNQ-1-1/8 time-delay midget fuses, each with a current rating of 1.125 A and voltage rating of 500 VAC.

Is FNQ-1-1/8*10pcs the manufacturer's model number?
No. The manufacturer model number is FNQ-1-1/8. The additional 10PCS designation indicates that the product listing contains ten pieces of the same fuse model.

What is the rated current of each fuse?
Each FNQ-1-1/8 fuse is rated at 1.125 A, equivalent to 1125 mA or one and one-eighth amperes.

Does a pack of 10 provide an 11.25 A fuse rating?
No. The 1.125 A rating applies to each individual fuse. Pack quantity does not change the current rating or operating characteristics of an individual fuse.

What is the AC voltage rating?
Each fuse has a maximum published voltage rating of 500 VAC.

Is FNQ-1-1/8 fast-acting or time-delay?
It is a time-delay fuse intended for compatible circuits where temporary inrush current may occur. Application suitability must be checked against the manufacturer's time-current characteristics.

What is the interrupting rating?
The FNQ-1-1/8 fuse has a published interrupting rating of 10 kA at 500 VAC, equivalent to 10,000 amperes.

What are the dimensions of each fuse?
Each fuse measures approximately 10.3 mm in diameter and 38.1 mm in length, corresponding to the standard midget cartridge format.

Does the fuse include a blown-fuse indicator?
No. FNQ-1-1/8 is a non-indicating cartridge fuse.

What is the construction of the fuse?
The FNQ series uses fiber tube construction and nickel-plated ferrule end caps. Series literature identifies nickel-plated brass end caps, while the individual product specification identifies nickel-plated bronze end caps.

Can FNQ-1-1/8 replace FNQ-R-1-1/8?
Do not assume the models are interchangeable. FNQ is a supplemental fuse series, whereas FNQ-R is a Class CC fuse series with different electrical protection classifications. Verify the equipment and fuse holder requirements before substitution.

What should be checked before ordering the 10-piece set?
Confirm the FNQ-1-1/8 model number, required quantity of 10 pieces, 1.125 A current rating per fuse, 500 VAC voltage rating, 10 kA interrupting rating, time-delay characteristics and compatibility with the intended fuse holder. Consult Eaton Bussmann FNQ Technical Data 1012 for application specifications.
