Key Features

0.3 A Current Rating

Rated at 0.3 amperes (300 mA), the Bussmann FNQ-R-3/10 provides Class CC overcurrent protection for appropriately designed low-current industrial control and electrical circuits.

600 VAC Voltage Rating

Designed for compatible AC electrical circuits operating at or below 600 VAC. The voltage rating supports suitable industrial control and branch-circuit applications.

Time-Delay Performance

Provides time-delay characteristics for circuits with temporary inrush currents, including compatible small control transformers. Eaton lists a response time of 12 seconds at 200% of rated current for this model.

200 kA Interrupting Capacity

Features a manufacturer-specified interrupting rating of 200,000 A RMS symmetrical at 600 VAC, subject to proper fuse selection and circuit installation.

Current-Limiting Class CC Design

Combines current-limiting performance with Class CC branch-circuit protection and a rejection-style cartridge configuration for use in compatible industrial fuse holders.

Compact Melamine Cartridge

Features a melamine tube body, non-indicating operation and ferrule end connections in a nominal 10.3 x 38.1 mm cartridge format suitable for appropriately rated Class CC fuse holders.

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 DIN-rail fuse holders and fuse blocks
Exact-model industrial equipment fuse replacement

Frequently Asked Questions

What is the Bussmann FNQ-R-3/10?
It is a 0.3 A, 600 VAC Class CC time-delay cartridge fuse from the Eaton Bussmann LIMITRON FNQ-R series, designed for compatible branch-circuit and industrial control applications.

Who manufactures FNQ-R-3/10?
FNQ-R-3/10 belongs to the Eaton Bussmann product range. Its manufacturer catalog number is FNQ-R-3/10.

What is the current rating?
The rated current is 0.3 amperes, equivalent to 300 milliamperes or three-tenths of an ampere.

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

Is FNQ-R-3/10 a time-delay fuse?
Yes. It is designed for compatible circuits with temporary inrush currents. Eaton lists a response time of 12 seconds at 200% of rated current for this model.

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-3/10 have a blown-fuse indicator?
No. Eaton identifies FNQ-R-3/10 as a non-indicating cartridge fuse.

What material and connection type does this fuse use?
Eaton specifies a melamine tube body and ferrule-to-ferrule connections. The product also features a Class CC rejection-style design.

Can FNQ-R-3/10 replace FNQ-3/10?
Do not assume interchangeability. FNQ-R-3/10 is a 600 VAC Class CC branch-circuit fuse rated for 200 kA interrupting capacity, whereas FNQ-3/10 belongs to the 500 VAC supplemental fuse series. Their protection classifications and installation requirements differ.

Is FNQ-R-3/10 RoHS compliant?
Eaton FNQ-R Technical Data 1014 lists the FNQ-R series as RoHS compliant, with an exception for FNQ-R-1/4. FNQ-R-3/10 is not identified as an exception in that document.

What should be verified before ordering?
Confirm the exact FNQ-R-3/10 model number, 0.3 A current rating, 600 VAC voltage rating, 200 kA interrupting capacity, time-delay characteristics, Class CC fuse-holder compatibility and applicable compliance requirements. Consult Eaton Bussmann FNQ-R Technical Data 1014.
