The overall load through the circuit should be about 80% of the rating of the fuse. Hope this helps. **Q: is the fuse for output power to the accessory ?** A: The fuse is protecting the source voltage supply on the #30 terminal. In theory this also protests the accessory wired to the #87 terminal because if the source sees a spike and blows the fuse the output will not see any current. To be safe you can also fuse anything connected to the accessory side of the relay on the #87 terminal independently. **Q: I have two 18w led aux lights hooked up to ome of these and its jimped into my parking lights. Why is ut buzzing?** A: The only thing i can think is the holding coil. Do the lights flicker **Q: These relays have built -in peak suppression diode?** A: No, these relays do not have built in flyback diodes. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on 24 September 2022* Good product ### ⭐⭐⭐⭐⭐ Review *by M***3 on 26 March 2026* Works great! ### ⭐ Review *by I***M on 6 May 2024* Be very very careful wired incorrectly, i had to pry the wires out the connector and switch them around to colour match correctly as shown in picture, manufacturer issue ## Frequently Bought Together - True MODS 6 Pack 4-Pin 12V Bosch Style Fused Relay Switch Kit [Interlocking Harness Socket Holder] [14 AWG Hot Wires] [SPST] [30 Amp] 12 Volt Automotive relays with Fuse for Auto Cars - irhapsody 5 Pack 40/30 AMP 12V DC Waterproof Relay and Harness - Heavy Duty 12 AWG Tinned Copper Wires, 5-PIN SPDT Automotive Relay - DaierTek 12V Relay Box 6 Way Relay Fuse Box 12 AWG Pre-Wired Waterproof Relay Box 6 Slot ATC/ATO Fuse Relay Block Universal Relay Panel for Automotive Car Marine Boat --- ## 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.sc/products/318576443-ols-6-pack-30a-fuse-relay-switch-harness-set-12v](https://www.desertcart.sc/products/318576443-ols-6-pack-30a-fuse-relay-switch-harness-set-12v) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-05-11*
