The size and specs were a perfect match, and my vacuum was up and running again in minutes. It’s great to have a pack of these on hand—especially during pool season when downtime is the last thing you want. The quality seems solid, and they came well-packaged with no broken or bent pins. If your Aquabot stops working and you suspect a fuse issue, these are a great, affordable fix. Highly recommend. ## Frequently Bought Together - BOJACK 5x20 mm 3 A 3 amp 125 V 125 Volt 0.2x0.78 Inch F3AL125V Fast-Blow Glass Fuses (Pack of 10) - BOJACK 5x20mm 5A 5amp 250V 0.2x0.78 Inch F5AL250V Fast-Blow Glass Fuses (Pack of 20) - BOJACK 6x30mm 3 A 3 amp 250 V 0.24x1.18 Inch Volt F3AL250V Fast-Blow Glass Fuses (Pack of 18) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/166093509-5x20-mm-3-a-3-amp-125-v-125-volt](https://www.desertcart.co.uk/products/166093509-5x20-mm-3-a-3-amp-125-v-125-volt) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-22*
