Keep your wiring safe with the genuine 40-amp blade fuse — Part No. RAC00141 (suffix /A). Officially labeled “FUSE, BLADE – 40A,” this is a standard ATO/ATC-size automotive blade fuse built to Royal Enfield specifications. Because it’s a universal electrical component, it isn’t restricted to a single motorcycle: use it on many Royal Enfield models (where the owner’s manual/fuse box calls for a 40A blade) and other 12V motorcycles or scooters that specify the same rating and size.

Typical placement is the main fuse near the battery/relay block, but some bikes also use 40A positions for high-draw accessories. Replace like-for-like only—never up-rate to “stop it blowing,” as that risks loom/ECU damage. This OE fuse offers consistent melt curves, correct blade thickness for snug fit in the holder, and durable element construction. Toss a spare in your tool kit to avoid roadside downtime. (We list models generically to reduce returns—always follow your bike’s manual or VIN fiche for the correct amperage and part number.)

FAQs 

1) Is RAC00141 a standard size?
Yes—ATO/ATC blade (standard automotive), 40A rating. Fits any holder designed for this format.

2) Which Royal Enfield models can use it?
Many do for the main fuse or high-draw circuits. Because specs vary by year/market, use it wherever your RE documentation says “Blade 40A.”

3) Can I replace a blown 40A with 30A or 50A?
No—always replace like-for-like (40A). Up- or down-rating can cause repeat failures or loom/ECU damage.

4) Will this work on non-RE motorcycles or cars?
Yes—if they specify a 40A ATO/ATC blade fuse. It’s a universal electrical part.

5) Where is the 40A fuse usually located?
Commonly near the battery/relay block or in the primary fuse box. Check your owner’s manual for the exact slot.

6) Do I need to diagnose why the fuse blew?
Absolutely. A blown main fuse often indicates a shorted wire, faulty accessory, or chafed harness. Fix root cause before riding.
