Rated at one-half ampere (500 mA), the Bussmann FNQ-R-1/2 provides Class CC overcurrent protection for appropriately designed low-current industrial electrical and control circuits.
Designed for compatible AC circuits operating at or below 600 VAC. The voltage rating supports appropriately specified industrial control and branch-circuit protection applications.
Designed to accommodate temporary inrush currents associated with compatible control transformers. Eaton specifies a response time of 12 seconds at 200% of rated current for this model.
Features a manufacturer-specified interrupting rating of 200,000 A RMS symmetrical at 600 VAC, suitable for installations where the protection requirements and available fault current have been properly evaluated.
Combines current-limiting performance with Class CC branch-circuit protection and a rejection-style cartridge design intended for compatible industrial fuse holders.
Features a melamine tube body, non-indicating operation and ferrule end connections in a nominal 10.3 x 38.1 mm cartridge format.

What is the Bussmann FNQ-R-1/2?
It is a 0.5 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-1/2?
FNQ-R-1/2 belongs to the Eaton Bussmann product range. Its manufacturer catalog number is FNQ-R-1/2.
What is the current rating?
The rated current is 0.5 amperes, equivalent to 500 milliamperes or one-half ampere.
What is the AC voltage rating?
The maximum published AC voltage rating is 600 VAC. The application circuit must remain within the fuse's specified voltage rating.
Is FNQ-R-1/2 a time-delay fuse?
Yes. It is designed for compatible circuits with temporary inrush currents. Eaton specifies 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-1/2 have a blown-fuse indicator?
No. Eaton identifies FNQ-R-1/2 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 fuse incorporates a Class CC rejection-style design.
Can FNQ-R-1/2 replace FNQ-1/2?
Do not assume interchangeability. FNQ-R-1/2 is a 600 VAC Class CC branch-circuit fuse rated for 200 kA interrupting capacity, whereas FNQ-1/2 belongs to the 500 VAC supplemental fuse series. Their protection classifications and installation requirements differ.
Is FNQ-R-1/2 RoHS compliant?
Yes. Eaton lists FNQ-R-1/2 as RoHS compliant. The FNQ-R Technical Data 1014 identifies FNQ-R-1/4 as the exception to the series RoHS statement, not FNQ-R-1/2.
What should be verified before ordering?
Confirm the exact FNQ-R-1/2 model number, 0.5 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.
