Key Features

100 mA Current Rating

Rated at 0.1 A (100 mA), the FNQ-1/10 is intended for compatible low-current industrial control circuits requiring supplemental overcurrent protection.

500 VAC Voltage Rating

Designed for AC circuits operating at or below its specified 500 VAC maximum voltage rating. The FNQ series uses an orange color code to identify the voltage class.

Time-Delay Operation

Its time-delay characteristic helps accommodate temporary inrush currents in compatible motor control transformer circuits and other equipment, subject to the manufacturer's time-current data.

10 kA Interrupting Rating

Provides a published interrupting capacity of 10,000 A at 500 VAC. The available short-circuit current at the installation must not exceed the applicable interrupting rating.

Compact Midget Fuse Design

The nominal 10.3 mm diameter and 38.1 mm length support installation in appropriately rated and dimensionally compatible midget fuse holders and blocks.

Fiber Tube and Metal End Caps

Manufactured with fiber tube construction and nickel-plated brass end caps, as described in the Eaton FNQ series technical data.

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 a 100 mA time-delay fuse
Control circuit maintenance and protective device replacement
Compatible DIN-rail midget fuse holders and blocks
Panel-mounted fuse holders and suitable industrial fuse clips

Frequently Asked Questions

What is the Bussmann FNQ-1/10?
It is a 100 mA, 500 VAC time-delay midget cartridge fuse from the Eaton Bussmann FNQ series, designed for supplemental overcurrent protection.

Who manufactures FNQ-1/10?
FNQ-1/10 is part of the Eaton Bussmann fuse range. Its manufacturer catalog number is FNQ-1/10.

What is its rated current?
The rated current is 0.1 amperes, equivalent to 100 milliamperes or one-tenth of an ampere.

What is the AC voltage rating?
The maximum published AC voltage rating is 500 VAC. The orange FNQ series color code identifies this voltage class.

Is FNQ-1/10 a fast-acting fuse?
No. FNQ-1/10 is a time-delay fuse designed for circuits where temporary inrush currents may occur. Its suitability must be assessed using the published time-current characteristics.

What is the interrupting rating?
Eaton Technical Data 1012 specifies an interrupting rating of 10 kA at 500 VAC for the FNQ series, including FNQ-1/10.

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

Does FNQ-1/10 have a blown-fuse indicator?
No. FNQ-1/10 is a non-indicating cartridge fuse.

What materials are used in the fuse?
Eaton FNQ Technical Data 1012 specifies fiber tube construction and nickel-plated brass end caps.

Can FNQ-1/10 replace an FNQ-R-1/10 fuse?
Do not assume the two models are interchangeable. FNQ is a supplemental fuse series, whereas FNQ-R is a Class CC fuse series. Their protection classifications and application requirements must be checked before substitution.

Can FNQ-1/10 be used for branch-circuit protection?
FNQ-1/10 is a supplemental overcurrent protection fuse. Applications requiring branch-circuit protection must use a properly classified protective device with an adequate interrupting rating.

What should be verified before ordering?
Confirm the exact FNQ-1/10 part number, 100 mA current rating, 500 VAC voltage rating, 10 kA interrupting capacity, time-delay characteristics, dimensions and fuse-holder compatibility. Consult Eaton Bussmann Technical Data 1012 for series specifications.
