Designed for automotive split charging and high current applications, it features precise voltage thresholds and durable M8 stud terminals, ensuring reliable, long-lasting operation in extreme conditions. ## Description 12 V DC 250 Amp Split Charge Relay Heavy Duty 4 Pin SPST (Single Pole Single Throw) relay Nominal coil voltage: 12 V DC Pickup voltage: 8 V DC Dropout voltage: 1.2 V DC Maximum applied voltage: 14 V DC Max Switching Current: 250A Max Switching Voltage: 14 V DC Temperature Range: -30 ~ +80 degrees Celsius Feature 1), Advantage - coil power: 1.8W; coil resistance: 80 ohms. It is more reliable than 2.4W (60 ohms) and 4.8W (30 ohms) relays on the market. 2), Large capacity: 250 amp high current carrying capacity, heavy duty make/break relay. 3), Ideal for split charging or any vehicle needing a high power relay. Package Content: 1 x 250 Amp 4 Pin Relay Review: Been installed for 3 years. Good solid product - Put this relay in my truck. Attached it so the auxiliary power closes the circuit. So I could run off road lighting. Been installed for about 3 years now. Solid and trust worthy for me. Review: Internal review of relay switch - If you are wondering exactly what this relay provides in terms of electrical design and implementation. Delighted to find solid copper internals, terrific dual brade, very flexible, stranded, woven ~8 AWG copper conductors from terminal #30 , a ~1/4 inch copper lug to activated contact. Terminal 87 of relay switch side provides a solid bar of copper rod 0.35 diameter with high temp contact on switch end. Plated high temp contacts are on both sides of high current switch as activated by relay. Relay operates well at 10 to 12 volts, with crisp aligned and swift magnetic force closure of switch. No bounce. Relay appears to be ok margin at up to maybe 220 volts as the base of the relay depends upon a piece of 0.07 inch thick plastic as isolation from 12 volt enamel coated solenoid wires AWG ~ #34 as connected to pins 85 and 86. Thermoplastic is higher temp, suitable wall strength, leg mount points may soften or melt at continuous duty of max current rating of device. For my application to deliver 200 A in a few milliseconds the device is well suited. YMMV ## Features - Our coil power is 1.8W, and coil resistance is 80ohms. It is more reliable than 2.4W (60 ohms) and 4.8W (30 ohms) relays on the market - Large capacity, high current carrying capacity, heavy-duty make/break relay. But never go beyond its capabilities, try to stay 10 to 15% below what the rate is for - Rated voltage: 12vdc; Pickup voltage: 8v; Dropout voltage: 1.2v - The size of the round stud terminals: M8/8mm - Ideal for split charging or any vehicle needing a high power relay ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08F28SKX1 | | Best Sellers Rank | #5,588 in Automotive ( See Top 100 in Automotive ) #3 in Automotive Replacement Accessory Power Relays | | Brand | iRhapsody | | Brand Name | iRhapsody | | Coil Resistance | 80 ohm | | Coil Voltage | 12 volts | | Connector Type | Quick Connect | | Contact Current Rating | 250 A | | Contact Material | Copper | | Contact Type | Normally Open | | Current Rating | 250 A | | Customer Reviews | 4.7 out of 5 stars 253 Reviews | | Manufacturer | IRHAPSODY | | Minimum Switching Voltage | 8 volts_of_direct_current | | Model | AutoRelay-12V250A1P | | Mounting Type | Screw Mount | | Number of Items | 1 | | Operation Mode | Off | | Part Number | AutoRelay-12V250A1P | | Warranty Description | 1 year | | Wattage | 1.8 watts | ## Product Details - **Connector Type:** Quick Connect - **Contact Material:** Copper - **Contact Type:** Normally Open - **Current Rating:** 250 A - **Mounting Type:** Screw Mount ## Images ![250A Relay, 12VDC Continuous Duty SPST 4-pin High Power Relay - Image 1](https://m.media-amazon.com/images/I/71ajAd5N8vL.jpg) ![250A Relay, 12VDC Continuous Duty SPST 4-pin High Power Relay - Image 2](https://m.media-amazon.com/images/I/61k+UtP0mPL.jpg) ![250A Relay, 12VDC Continuous Duty SPST 4-pin High Power Relay - Image 3](https://m.media-amazon.com/images/I/6186S5yPs5L.jpg) ![250A Relay, 12VDC Continuous Duty SPST 4-pin High Power Relay - Image 4](https://m.media-amazon.com/images/I/61Hvct-P3jL.jpg) ![250A Relay, 12VDC Continuous Duty SPST 4-pin High Power Relay - Image 5](https://m.media-amazon.com/images/I/51DHN3EXisL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Been installed for 3 years.
