Damage Limits: 100g Hunidity: 40% ~ 85% Insulation Resistance: 100mΩ Min at500VDC Dielectric Strength Between Open Contacts: 500VAC (for one minute/sec) Between Contactw and coil: 750AC (for one minute/sec) Operate Tice: 7ms Release Tice: 5ms Package Content: 1 x 12VDC waterproof relay kit ## Features - Never go beyond its capabilities. Try to stay 10 to 15% below what the rate is for - 12-volt 5-prong (SPDT) relay. Excellent water-repellent and dustproof ability, but do not use it in water - Be careful when plugging the relay into the socket. If you push hard, you will bend the female connector - Primary leads use 12 a.w.g tinned copper wire. Coil leads use 16 a.w.g - SPDT relay: it has both normally open and normally closed terminals, terminal 87A is powered when the relay is inactive and switches the power to terminal 87 when the relay is activated ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B074QV54V1 | | Best Sellers Rank | #33,697 in Automotive ( See Top 100 in Automotive ) #26 in Automotive Replacement Accessory Power Relays | | Brand Name | iRhapsody | | Coil Resistance | 80 ohm | | Coil Voltage | 12 volts | | Connector Type | Plug-In | | Contact Current Rating | 30 A | | Contact Material | Copper | | Contact Type | Normally Open, Closed | | Current Rating | 30 A | | Customer Reviews | 4.6 4.6 out of 5 stars (2,318) | | Manufacturer | IRHAPSODY | | Maximum Switching Current | 40 A | | Minimum Switching Voltage | 6 volts_of_direct_current | | Model | Relay-4V1 | | Mounting Type | Socket Mount | | Number of Items | 1 | | Operation Mode | Automatic | | Part Number | IY-5PinRelay-1 | | Warranty Description | 1 YEAR WARRANTY | | Wattage | 1.8 watts | ## Product Details - **Connector Type:** Plug-In - **Contact Material:** Copper - **Contact Type:** Normally Open, Closed - **Current Rating:** 30 A - **Mounting Type:** Socket Mount ## Images ![5-pin 40/30Amp 12V DC Waterproof Automotive Relay with Heavy-Duty Wire - Image 1](https://m.media-amazon.com/images/I/41jiCa7HfGL.jpg) ![5-pin 40/30Amp 12V DC Waterproof Automotive Relay with Heavy-Duty Wire - Image 2](https://m.media-amazon.com/images/I/41SzDZQ2ENL.jpg) ![5-pin 40/30Amp 12V DC Waterproof Automotive Relay with Heavy-Duty Wire - Image 3](https://m.media-amazon.com/images/I/41Z2aFqidyL.jpg) ![5-pin 40/30Amp 12V DC Waterproof Automotive Relay with Heavy-Duty Wire - Image 4](https://m.media-amazon.com/images/I/412i5JJWayL.jpg) ![5-pin 40/30Amp 12V DC Waterproof Automotive Relay with Heavy-Duty Wire - Image 5](https://m.media-amazon.com/images/I/41tafw86B6L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this solid state?** A: It has only an electromagnet (coil) which when activated pulls an armature which pulls contacts together, completing the circuit. Basically it is a switch. This is not transistorized **Q: Where are these relays made?** A: Based on the price I assume they are made in china. They are high quality. I run them on my race car and haven't had a problem. **Q: Will this relay work on a mercury force outboard 40hp 1998?** A: This is a universal 12v relay u will need to wire to it what ever you want to operate It's not a specific relay to you application **Q: How long does it take to ship** A: Few days ## Frequently Bought Together - irhapsody 1 Pack 40/30 AMP 12V DC Waterproof Relay and Harness - Heavy Duty 12 AWG Tinned Copper Wires, 5-PIN SPDT Automotive Relay - Compliance Parts LMC5 Module - C5 Corvette steering column lock bypass module Black --- ## 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.za/products/47483866-5-pin-40-30amp-12v-dc-waterproof-automotive-relay-heavy](https://www.desertcart.co.za/products/47483866-5-pin-40-30amp-12v-dc-waterproof-automotive-relay-heavy) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-20*
