## **IEC Low Voltage General Purpose Protection - Ferrule fuse links** ~~**8x31 gG 400VAC from 0.5 to 25A**~~ ~~Ferraz Shawmut aM and gG fuse-links cover a wide range of physical sizes and ampere~~ ratings for 400, 500, and 690VAC for protection in electrical distribution circuits and various industrial applications. Most ratings are available in size 8x31 and size 10x38 with an optional indicator, and in size 14x51 and 22x58 with an optional striker to activate an auxiliary contact. All cylindrical fuse-links have ceramic bodies and silver-plated ferrules. Our technology and process was designed to ensure highly reliable technical performance. ## **Benefits** Small size Full range protection Safest and most reliable protection system High limiting and breaking capacity Visual blown fuse indication Low power dissipation ## **Applications** gG type for protection of line, cable against overload and short circuit in various industrial application and electrical distribution circuits. ## **Ratings** 400VAC 0.5 to 25A 20kA breaking capacity Size Rated Nominal Class Catalog Number Reference Catalog Number Reference Voltage Current w/o indicator Number w/o with indicator Number with (V) (A) indicator indicator ~~ee~~ 8x31 400 0.5 gG FR8GG40V0.5 ~~GO~~ P218191 - - ~~Re~~ 8x31 400 1 gG ~~GO~~ FR8GG40V1 C218709 - - ~~Re~~ 8x31 400 2 gG FR8GG40V2 ~~GO~~ Q219227 FR8GG40V2I B222204 ~~OO~~ 8x31 400 4 gG FR8GG40V4 W222958 FR8GG40V4I X222959 ~~ee~~ 8x31 400 ~~OO~~ 6 gG FR8GG40V6 A211025 FR8GG40V6I V201291 ~~OO~~ 8x31 400 8 gG FR8GG40V8 B213096 FR8GG40V8I B211026 ~~a~~ 8x31 400 10 gG FR8GG40V10 A214613 FR8GG40V10I A212060 8x31 400 12 gG FR8GG40V12 R216146 FR8GG40V12I C213097 ~~a~~ 8x31 400 16 gG FR8GG40V16 P216650 FR8GG40V16I Y214105 ~~a~~ 8x31 ~~GO~~ 400 20 gG FR8GG40V20 F217677 FR8GG40V20I J215127 8x31 400 25 gG FR8GG40V25 D218710 FR8GG40V25I S216147 ~~Re eG GO~~ ## **Standards & Approvals** IEC 60269-1 & -2 RoHS Compliant ## **Related products** Fuse-holders: Modulostar® CMS8 **==> picture [254 x 100] intentionally omitted <==** **----- Start of picture text -----**<br> Dimensions (mm) Blown fuse indicator<br>B % y<br>Size A B C<br>8x31 8.5 31.5 6.7<br>Before After<br>**----- End of picture text -----**<br> Material body: Ceramic Material contact: Silver plated copper Product weight: 4.4g Packaging: 10 pieces ## **IEC Low Voltage General Purpose Protection - Ferrule fuse links** ~~**8x31 gG 400VAC from 0.5 to 25A**~~ |Size|Rated<br>Voltage (V)|Nominal<br>Current (A)|Breaking Capacity @<br>Rated Voltage (kA)|Watts Loss @<br>100% In (W)| |---|---|---|---|---| |||||| |8x31|400|0.5|20|0.55| |8x31|400|1|20|0.35| |8x31|400|2|20|0.45| |8x31|400|4|20|0.06| |8x31|400|6|20|0.83| |8x31|400|8|20|1| |8x31|400|10|20|1.2| |8x31|400|12|20|1.3| |8x31|400|16|20|1.7| |8x31|400|20|20|2| |8x31|400|25|20|2.4| ## **Characteristics I²t** **==> picture [176 x 186] intentionally omitted <==** **----- Start of picture text -----**<br> Clearing I²t (A²s)Prearcing and 57<br>3<br>2<br>1<br>07<br>05<br>03<br>0.2<br>O41<br>0.07 foal<br>0.05<br>0.03<br>0.02<br>woS - N + o (-) i=)= Nn=<br>Nominal Current (A)<br>**----- End of picture text -----**<br> ## **IEC Low Voltage General Purpose Protection - Ferrule fuse links** ~~**8x31 gG 400VAC from 0.5 to 25A**~~ ## ~~**Time current characteristics**~~ **==> picture [52 x 16] intentionally omitted <==** **----- Start of picture text -----**<br> Actual prearcing<br>time (s)<br>**----- End of picture text -----**<br> rms value of prearc current (A) ± 10% ## **Peak let thru characteristics** **==> picture [264 x 121] intentionally omitted <==** **----- Start of picture text -----**<br> Maximum peak let<br>a<br>thru current (A) 200<br>400.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 540,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
