Key Features

1 A Current Rating

Rated at 1 ampere, the Bussmann FNQ-R-1 provides Class CC overcurrent protection for appropriately designed low-current 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. The voltage rating supports appropriately specified industrial control and branch-circuit protection applications.

High-Inrush Time-Delay Performance

The time-delay characteristic is intended to accommodate temporary magnetizing inrush currents associated with small control transformers. Eaton lists a response time of 12 seconds at 200% of rated current for this model.

200 kA Interrupting Capacity

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

Current-Limiting Class CC Design

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

Compact Melamine Cartridge

Features a melamine tube body, dual-element design, non-indicating operation and ferrule end connections in a nominal 10.3 x 38.1 mm cartridge format for industrial control equipment.

Applications

Small industrial control transformer protection
Industrial control panels requiring Class CC fuses
Compatible low-current AC branch circuits
Electrical line protection applications
Control circuits with temporary transformer inrush currents
Industrial machinery control equipment
Compatible Class CC fuse holders and fuse blocks
Exact-model industrial equipment fuse replacement

Frequently Asked Questions

What is the Bussmann FNQ-R-1?
It is a 1 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?
FNQ-R-1 belongs to the Eaton Bussmann product range. Its manufacturer catalog number is FNQ-R-1.

What is the current rating?
The rated current is 1 ampere, equivalent to 1,000 milliamperes.

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

Is FNQ-R-1 a time-delay fuse?
Yes. FNQ-R-1 is a time-delay, dual-element fuse designed for compatible applications involving temporary inrush currents. Eaton's 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 have a blown-fuse indicator?
No. Eaton identifies FNQ-R-1 as a non-indicating cartridge fuse without a built-in visual blown-fuse indicator.

What material and terminal configuration does FNQ-R-1 use?
Eaton specifies a melamine tube body and ferrule-to-ferrule connections. The fuse incorporates a rejection-style Class CC cartridge design.

Can FNQ-R-1 replace FNQ-1?
Do not assume interchangeability. FNQ-R-1 is a 600 VAC Class CC branch-circuit fuse with a 200 kA interrupting rating, whereas FNQ-1 belongs to the 500 VAC supplemental fuse series. Their protection classifications, physical rejection features and installation requirements differ.

Is FNQ-R-1 RoHS compliant?
Yes. Eaton lists FNQ-R-1 as RoHS compliant and CE marked. The FNQ-R series technical data identifies FNQ-R-1/4, not FNQ-R-1, as the exception to its RoHS compliance statement.

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