Littelfuse FLQ-10 FLQ10 10 Amp 10A 500Vac Fuses TIME DELAY Fuse

Littelfuse FLQ-10 (FLQ010) 10A Time-Delay Midget Fuse

Buy Littelfuse FLQ-10 fuse online.The Littelfuse FLQ-10, officially cataloged as FLQ010, is a 10 amp, 500Vac and 300Vdc time-delay supplemental midget fuse designed for control power transformers, solenoids, high-inrush circuits and small motor applications.

Part of the Littelfuse POWR-GARD® FLQ series, this non-indicating fuse uses a compact 10 × 38 mm cylindrical format. Its time-delay operating characteristic allows temporary startup and inrush current to pass for a limited period while providing supplemental overcurrent protection for properly rated equipment and internal circuits.

• Solenoid circuits
• Circuits with temporary high inrush current
• Small motor supplemental protection
• Industrial control equipment
• Machine control panels
• Replacement applications that specify FLQ010

Time-Delay Protection for High-Inrush Loads

Control transformers, solenoids and small motors can draw temporary current surges when energized. A fast-acting fuse may open during normal startup if it is not designed to tolerate the expected inrush current.

The Littelfuse FLQ010 uses a time-delay response that allows a temporary overload or startup surge to pass for a limited period without opening. This makes it suitable for equipment that specifically requires a 10 amp FLQ-series time-delay fuse.

500Vac and 300Vdc Ratings

The FLQ010 is rated for systems operating at up to 500Vac and 300Vdc. Its published interrupting rating is 10kA RMS symmetrical for AC applications and 10kA for DC applications, with the DC performance self-certified by Littelfuse.

The applied voltage and available fault current must remain within the published ratings of both the fuse and the installed fuse holder. Confirm all system specifications before installation.

Supplemental Overcurrent Protection

The FLQ010 is classified as a supplemental midget fuse. It is intended to provide additional overcurrent protection within equipment or in circuits where supplemental protection is permitted.

It should not automatically be substituted for a required branch-circuit fuse. The equipment manufacturer's documentation and applicable electrical requirements should determine the correct fuse category.

Compact 10 × 38 mm Construction

The FLQ010 uses a standard 10 × 38 mm cylindrical cartridge format. Its compact dimensions support installation in compatible fuse blocks, clips and holders used in industrial control equipment and electrical panels.

The 10A version uses a melamine body with nickel-plated copper-alloy caps. Physical fit alone does not establish electrical interchangeability with other 10 × 38 mm fuses.

Compatible Littelfuse Fuse Holders

Littelfuse identifies the LPSM dead-front fuse holder series and L60030M open-face fuse holder series as accessories for FLQ midget fuses. The exact holder configuration must be selected according to the required pole count, terminal style, mounting method and electrical ratings.

FLQ010 and FLQ-10 Model Identification

The official Littelfuse catalog number is FLQ010. The hyphenated format FLQ-10 is commonly used in searches and product descriptions to represent the same 10 amp FLQ rating.

For purchasing, inventory and Google Merchant Center data, use FLQ010 as the manufacturer part number. Always compare the complete product marking and ordering information before replacing an existing fuse.

Not a Direct Class CC Replacement

The FLQ010 is listed by Littelfuse as a supplemental midget fuse. It should not be marketed as a direct replacement for a rejection-style Class CC branch-circuit fuse solely because both products may use a similar cylindrical format.

Current rating, voltage rating, time-current response, interrupting rating, approval category and holder compatibility must all be checked before substitution.

Certifications and Compliance

• UL Listed, File E10480
• CSA Certified, File LR29862
• CE documentation available
• RoHS compliant

Important Selection Information

Before purchasing, confirm the official catalog number FLQ010, the required 10 amp rating, system voltage, available fault current, time-delay requirement and fuse-holder compatibility.

Do not select a replacement fuse solely by amperage, appearance or physical dimensions. The voltage rating, fuse category, opening characteristic, interrupting rating and equipment requirements must also match the application.

Ordering Information

Order using Littelfuse catalog number FLQ010 or ordering number 0FLQ010.T. Confirm the required quantity, product condition and all electrical specifications before purchase or installation.
