Key Features

800 mA Current Rating

Rated at 0.8 A (800 mA), the FNQ-8/10 provides supplemental overcurrent protection for appropriately specified low-current industrial electrical control circuits.

500 VAC Voltage Rating

Designed for compatible AC control and equipment circuits operating at or below the published maximum voltage rating of 500 VAC. The FNQ series uses an orange voltage-class color code.

Time-Delay Operation

Helps accommodate temporary inrush currents associated with motor control transformers and compatible inductive loads, subject to the manufacturer's published time-current characteristics.

10 kA Interrupting Rating

Features a manufacturer-specified interrupting rating of 10,000 A at 500 VAC. The available short-circuit current must not exceed the fuse's applicable interrupting capacity.

Compact Midget Fuse Format

Uses a nominal 10.3 mm diameter and 38.1 mm length cylindrical cartridge design for installation in appropriately rated and dimensionally compatible midget fuse holders.

Industrial Cartridge Construction

Combines fiber tube construction, non-indicating operation and nickel-plated ferrule connections. Eaton's product specification identifies nickel-plated bronze end caps.

Applications

Motor control transformer supplemental protection
Industrial AC control circuits with temporary inrush currents
Compatible low-current transformer primary circuits
Industrial electrical control panels
Electrical equipment requiring an 800 mA time-delay fuse
Industrial automation control circuit maintenance
Compatible DIN-rail midget fuse holders and blocks
Equipment servicing and specified fuse replacement

Frequently Asked Questions

What is the Bussmann FNQ-8/10?
It is an 800 mA, 500 VAC time-delay midget cartridge fuse from the Eaton Bussmann FNQ series, intended for supplemental overcurrent protection.

Who manufactures FNQ-8/10?
FNQ-8/10 is part of the Eaton Bussmann fuse range. Its manufacturer catalog number is FNQ-8/10.

What is the rated current?
The rated current is 0.8 amperes, equivalent to 800 milliamperes or eight-tenths of an ampere.

What is the AC voltage rating?
The maximum published AC voltage rating is 500 VAC. The FNQ series uses orange as its voltage-class color code.

Is FNQ-8/10 a fast-acting fuse?
No. FNQ-8/10 is a time-delay fuse intended for circuits where temporary inrush currents may occur. Its suitability should be evaluated using the manufacturer's published time-current characteristics.

What is the interrupting rating at 500 VAC?
Eaton specifies a 10 kA interrupting rating at 500 VAC for FNQ-8/10, equivalent to 10,000 amperes.

What are the physical dimensions?
The nominal dimensions are 10.3 mm in diameter and 38.1 mm in length, approximately 13/32 inch by 1-1/2 inches.

Does FNQ-8/10 have a blown-fuse indicator?
No. The standard FNQ-8/10 is a non-indicating cartridge fuse.

What materials are used in this fuse?
Eaton FNQ Technical Data 1012 identifies fiber tube construction and nickel-plated brass end caps for the series. The individual Eaton FNQ-8/10 product specification identifies nickel-plated bronze end caps.

Can FNQ-8/10 replace an FNQ-R-8/10 fuse?
Do not assume the two models are interchangeable. FNQ is a 500 VAC supplemental fuse series, whereas FNQ-R is a Class CC fuse series with different protection classifications and application requirements.

Can FNQ-8/10 be used for branch-circuit protection?
FNQ-8/10 is intended for supplemental overcurrent protection. Applications requiring branch-circuit protection must use an appropriately classified protective device with a suitable interrupting rating.

What should be verified before ordering?
Confirm the exact FNQ-8/10 model number, 800 mA current rating, 500 VAC voltage rating, 10 kA interrupting capacity, time-delay characteristics, physical dimensions and fuse-holder compatibility. Consult Eaton Bussmann FNQ Technical Data 1012 for series specifications.
