Key Features

10 A Current Rating

Rated at 10 amperes, the Bussmann FNQ-R-10 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, supporting industrial electrical line protection and branch-circuit applications where Class CC fuse protection is specified.

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. Actual opening behavior depends on the overcurrent level and the published time-current characteristics.

200 kA Interrupting Capacity

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

Current-Limiting Class CC Design

Combines current-limiting performance with Class CC branch-circuit protection. Its rejection-style design is intended for compatible fuse holders and helps prevent the installation of unsuitable supplemental fuses in rejection-style holders.

Compact Melamine Cartridge

Features a melamine tube body, dual-element construction, non-indicating operation and ferrule end connections. Its nominal 10.3 x 38.1 mm dimensions support installation in compatible Class CC fuse holders and fuse blocks.

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-10?
It is a 10 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-10?
FNQ-R-10 belongs to the Eaton Bussmann product range. Its manufacturer catalog number is FNQ-R-10.

What is the current rating?
The rated current is 10 amperes, equivalent to 10,000 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. Confirm any separate DC application requirements against manufacturer documentation.

Is FNQ-R-10 a time-delay fuse?
Yes. Eaton identifies FNQ-R-10 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 applied current and operating conditions.

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

What material and terminal configuration does FNQ-R-10 use?
Eaton specifies a melamine tube body and ferrule-to-ferrule connections. FNQ-R series documentation also describes nickel-plated brass end caps and dual-element current-limiting construction.

Can FNQ-R-10 replace FNQ-10?
Do not assume direct interchangeability. FNQ-R-10 is a 600 VAC Class CC branch-circuit fuse with a 200 kA interrupting rating, whereas FNQ-10 belongs to the 500 VAC supplemental fuse series. Their protection classifications, rejection features, time-current characteristics and fuse-holder requirements differ.

Is FNQ-R-10 RoHS compliant?
Yes. Eaton identifies FNQ-R-10 as RoHS compliant and CE marked. Confirm any additional application-specific compliance documentation required for installation.

What should be verified before ordering?
Confirm the exact FNQ-R-10 catalog number, 10 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.
