Frequently Asked Questions

What is the Bussmann FNQ-R-5-6/10?
It is a 5.6 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-5-6/10?
FNQ-R-5-6/10 belongs to the Eaton Bussmann fuse range. Its manufacturer catalog number is FNQ-R-5-6/10.

What is the current rating?
The rated current is 5.6 amperes, equivalent to 5600 milliamperes or five and six-tenths amperes.

What is the AC voltage rating?
The maximum published AC voltage rating is 600 VAC. The operating circuit voltage must remain within the fuse's applicable electrical rating.

Is FNQ-R-5-6/10 a time-delay fuse?
Yes. Eaton identifies FNQ-R-5-6/10 as a high-inrush time-delay fuse. The product specification lists a response time of 12 seconds at 200% of rated current. Actual opening time depends on current magnitude and the time-current characteristic.

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-5-6/10 have a blown-fuse indicator?
No. Eaton identifies FNQ-R-5-6/10 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 features a dual-element, current-limiting design and rejection-style Class CC cartridge construction.

Can FNQ-R-5-6/10 replace a standard FNQ series fuse?
Do not assume interchangeability based on current rating or cartridge size alone. FNQ-R-5-6/10 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. Their protection classifications, rejection features and application requirements differ.

Is FNQ-R-5-6/10 RoHS compliant?
Yes. Eaton's published product specification identifies FNQ-R-5-6/10 as RoHS compliant and CE marked. Confirm any additional application-specific compliance requirements before installation.

What should be verified before ordering?
Confirm the exact FNQ-R-5-6/10 catalog number, 5.6 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 for additional application guidance.
