Frequently Asked Questions

What is the Bussmann FNQ-R-1-6/10?
It is a 1.6 A, 600 VAC Class CC current-limiting time-delay cartridge fuse from the Eaton Bussmann LIMITRON FNQ-R series, designed for compatible industrial control and branch-circuit applications.

Who manufactures FNQ-R-1-6/10?
FNQ-R-1-6/10 belongs to the Eaton Bussmann product range. Its manufacturer catalog number is FNQ-R-1-6/10.

What is the current rating?
The rated current is 1.6 amperes, equivalent to 1600 milliamperes or one and six-tenths amperes.

What is the AC voltage rating?
The published AC voltage rating is 600 VAC. The operating circuit voltage must remain within the applicable fuse rating. A DC voltage rating is not specified by Eaton for this particular model.

Is FNQ-R-1-6/10 a time-delay fuse?
Yes. Eaton identifies FNQ-R-1-6/10 as a high-inrush time-delay fuse. Its product specification lists a response time of 12 seconds at 200% of rated current.

What is the interrupting rating?
Eaton specifies a 200 kA RMS symmetrical interrupting rating at 600 VAC, equivalent to 200,000 amperes.

What are the physical dimensions?
The nominal dimensions are 10.3 mm in diameter and 38.1 mm in length, approximately 0.41 inch by 1.50 inches.

Does FNQ-R-1-6/10 have a blown-fuse indicator?
No. Eaton identifies FNQ-R-1-6/10 as a non-indicating cartridge fuse without a built-in visual blown-fuse indicator.

What material and terminal configuration does this fuse use?
Eaton specifies a melamine tube body with ferrule-to-ferrule connections. The fuse uses a dual-element current-limiting design and a Class CC rejection-style cartridge configuration.

Can FNQ-R-1-6/10 replace an FNQ series fuse?
Do not assume interchangeability based on current rating or cartridge dimensions alone. FNQ-R-1-6/10 is a 600 VAC Class CC branch-circuit fuse with a 200 kA interrupting rating, whereas the FNQ series is intended for 500 VAC supplemental overcurrent protection. The classification, rejection features and applicable time-current characteristics must be evaluated.

Is FNQ-R-1-6/10 RoHS compliant?
Yes. Eaton identifies FNQ-R-1-6/10 as RoHS compliant and CE marked. Eaton FNQ-R Technical Data 1014 identifies FNQ-R-1/4 as the exception to its series RoHS compliance statement, not FNQ-R-1-6/10.

What should be verified before ordering?
Confirm the exact FNQ-R-1-6/10 catalog number, 1.6 A current rating, 600 VAC voltage rating, 200 kA interrupting capacity, time-delay characteristics, Class CC fuse-holder compatibility and applicable circuit protection requirements. Refer to Eaton Bussmann FNQ-R Technical Data 1014.
