Review: High quality product arrived in good new condition. - All pins and sockets were straight and tight. All leads had insulation separated at last 1/2 inch or so to ease installation. I used these relays to replace OEM relays and inline fuses in an off road LED lighting installation on an ATV. Very limited space available for installation. With an integrated fuse, these were smaller than the OEM relay with separate inline fuses, thereby reducing the overall space needed, allowing for a smaller electrical junction box to house them. These were every bit the quality I have come to expect from Bosch after 40 or so years in the auto repair business. They function fine and make almost no noise when activated. I am satisfied with this product. ## Features - Built in fuse socket with included 30A blade fuse with heavy duty 14AWG wires for main contact. - Bosch style 4-Pin SPST (Single Pole Single Throw) Relay. - 12VDC (14V Max) and 30A High Switching Capability. - Wire Specifications: Black - Ground (85), Red - VDC (30), White - Trigger (86), Blue - Output N/O (87). - Set includes 6 relays, 6 relay harnesses, and 6 blade fuses. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NBAO1SA | | Best Sellers Rank | #21,421 in Automotive ( See Top 100 in Automotive ) #10 in Automotive Replacement Starter Relays | | Brand | ONLINE LED STORE | | Brand Name | ONLINE LED STORE | | Coil Resistance | 80 milliohms | | Coil Voltage | 12 volts | | Connector Type | Quick Connect | | Contact Current Rating | 30 A | | Contact Material | Silver Plated Copper | | Contact Type | Normally Open | | Current Rating | 30 A | | Customer Reviews | 4.7 out of 5 stars 2,362 Reviews | | Item Weight | 12.8 ounces | | Manufacturer | ONLINE LED STORE | | Maximum Switching Current | 30 A | | Minimum Switching Voltage | 12 volts_of_direct_current | | Model | PSZACCEPS179R | | Mounting Type | Panel Mount | | Operation Mode | Automatic | | Part Number | PSZACCEPS179R | | UPC | 816165023880 | | Wattage | 18 watts | ## Product Details - **Connector Type:** Quick Connect - **Contact Material:** Silver Plated Copper - **Contact Type:** Normally Open - **Current Rating:** 30 A - **Mounting Type:** Panel Mount ## Images ![True MODS 6 Pack Bosch Style 4-Pin 12V Fused Relay Kit SPST 30 Amp | Interlocking Harness Socket, Fused, 14 AWG, SPST, 30 Amp, 12 Volt Automotive Relays, For Auto Car Truck Fan RV - Image 1](https://m.media-amazon.com/images/I/81FVp-H-BUL.jpg) ## Questions & Answers **Q: Can I use a smaller fuse?** A: Yes, you totally can. 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 ### ⭐⭐⭐⭐⭐ Good quality *by M***3 on March 26, 2026* Works great! ### ⭐⭐⭐⭐⭐ High quality product arrived in good new condition. *by J***S on November 10, 2020* All pins and sockets were straight and tight.

Having the fuse built into the relay is a cool feature. Wire is cca for those who are wondering. I have these powering low amp products( led lighting, starlight) and have no issues. Very happy with these relays. ## 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.com.cy/products/37076444-true-mods-6-pack-bosch-style-4-pin-12v-fused](https://www.desertcart.com.cy/products/37076444-true-mods-6-pack-bosch-style-4-pin-12v-fused) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-09-13*
