Frequently Asked Questions

What is the Littelfuse FLQ-3?
It is a 3 A time-delay midget fuse from the Littelfuse FLQ series, designed for supplemental overcurrent protection.

What is the rated current of FLQ-3?
The rated current is 3 amperes.

What is its AC voltage rating?
The rated AC voltage is 500 VAC or less.

Can the FLQ-3 be used in DC circuits?
The FLQ series is rated for 300 VDC. Verify circuit conditions and DC interrupting requirements before selecting the fuse.

Is FLQ-3 a fast-acting fuse?
No. It is a time-delay fuse designed to tolerate certain temporary inrush currents according to its time-current characteristics.

What are the fuse dimensions?
It belongs to the 10 x 38 mm midget fuse format. Check the holder dimensions and installation requirements before use.

What type of terminals does FLQ-3 use?
The standard FLQ-3 fuse uses ferrule-style end caps.

What is the interrupting rating?
The FLQ series is rated at 10 kA RMS symmetrical for AC applications and 10 kA for DC applications, with the DC rating self-certified by Littelfuse.

What materials are used in the fuse?
The published FLQ series specifications identify a paper body for the 3 A rating and nickel-plated copper-alloy end caps.

What applications are recommended?
Typical applications include control power transformers, solenoids and circuits with high temporary inrush currents.

Can FLQ-3 be used for branch-circuit protection?
The FLQ series is intended for supplemental overcurrent protection. Applications requiring branch-circuit protection should use a fuse with the appropriate classification and ratings.

What should be verified before ordering a replacement?
Confirm the exact model number, 3 A rating, operating voltage, interrupting capacity, time-delay requirements, physical dimensions and fuse-holder compatibility.
