Key Features

8 A Current Rating

Rated at 8 amperes, the Bussmann FNQ-R-8 provides Class CC overcurrent protection for appropriately specified industrial control circuits, small control transformers and compatible electrical equipment.

600 VAC Voltage Rating

Designed for compatible AC electrical circuits operating at or below 600 VAC. Its published voltage rating supports industrial electrical line protection and branch-circuit applications requiring a Class CC protective device.

High-Inrush Time-Delay Performance

The time-delay characteristic helps accommodate temporary magnetizing inrush currents associated with compatible small control transformers. Eaton lists a response time of 12 seconds at 200% of rated current for this model. Fuse selection should also consider the manufacturer's complete time-current characteristics.

200 kA Interrupting Capacity

Features a manufacturer-specified interrupting rating of 200,000 amperes RMS symmetrical at 600 VAC for appropriately engineered electrical circuits with evaluated prospective short-circuit current.

Current-Limiting Class CC Design

Combines current-limiting protection with Class CC branch-circuit classification. Its rejection-style construction is suitable for appropriately rated holders and helps prevent installation of incompatible supplemental fuses into rejection-style holders.

Compact Melamine Cartridge

Features a melamine tube body, dual-element construction, non-indicating operation and ferrule end connections. The nominal 10.3 x 38.1 mm cartridge format supports installation in compatible industrial Class CC fuse blocks and holders.

Applications

Small industrial control transformer protection
Industrial control panels requiring Class CC fuses
Compatible AC branch-circuit protection
Industrial electrical line protection
Control circuits with temporary transformer inrush currents
Industrial machinery control equipment
Compatible Class CC DIN-rail fuse holders and fuse blocks
Exact-model industrial equipment fuse replacement

Frequently Asked Questions

What is the Bussmann FNQ-R-8?
It is an 8 A, 600 VAC Class CC current-limiting time-delay cartridge fuse from the Eaton Bussmann LIMITRON FNQ-R series, intended for compatible industrial control and branch-circuit protection applications.

Who manufactures FNQ-R-8?
FNQ-R-8 belongs to the Eaton Bussmann product range. Its manufacturer catalog number is FNQ-R-8.

What is the current rating?
The rated current is 8 amperes, equivalent to 8000 milliamperes.

What is the AC voltage rating?
The published AC voltage rating is 600 VAC. The operating circuit voltage must remain within the fuse's applicable rating. Eaton FNQ-R Technical Data 1014 specifies DC ratings only for certain other amperage models, not FNQ-R-8.

Is FNQ-R-8 a time-delay fuse?
Yes. Eaton identifies FNQ-R-8 as a high-inrush time-delay fuse. Its product specification lists a response time of 12 seconds at 200% of rated current. Actual melting and clearing times depend on the operating conditions and applicable time-current curves.

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-8 have a blown-fuse indicator?
No. Eaton identifies FNQ-R-8 as a non-indicating cartridge fuse without a built-in visual blown-fuse indicator.

What material and terminal configuration does FNQ-R-8 use?
Eaton specifies a melamine tube body, ferrule-to-ferrule connections and a rejection-style Class CC cartridge configuration.

Can FNQ-R-8 replace FNQ-8?
Do not assume direct interchangeability. FNQ-R-8 is a 600 VAC Class CC branch-circuit fuse with a 200 kA interrupting rating, whereas FNQ-8 belongs to the 500 VAC supplemental fuse series. Their classifications, rejection features, time-current characteristics and fuse-holder requirements differ.

Is FNQ-R-8 RoHS compliant?
Yes. Eaton's FNQ-R-8 product page identifies the model as RoHS compliant and CE marked. The FNQ-R series technical data lists FNQ-R-1/4, not FNQ-R-8, as the RoHS exception.

What should be verified before ordering?
Confirm the exact FNQ-R-8 catalog number, 8 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 detailed application guidance.
