Description

BLARYETI 12V 40A Automotive Relay, 4-Pin SPST (Model JD1912) – Heavy Duty Rel.... The standard 4-prong layout ensures compatibility with most generic relay harnesses and fuse blocks. PRODUCT OVERVIEW: The BLARYETI JD1912 Automotive Relay is a heavy-duty single pole single throw (SPST) electrical switch designed for 12V DC vehicle systems. This 4-pin relay acts as a high-performance power gate, allowing low-amperage dashboard switches to safely activate high-amperage accessories. By isolating the heavy electrical load, it prevents voltage drop, protects original wiring harnesses from melting, and ensures maximum performance for connected devices. It is an essential component for any custom automotive electrical upgrade or replacement project. WIDE APPLICATION AND COMPATIBILITY: This universal 12V 40A relay is engineered to handle continuous high-power loads, making it the ideal solution for powering fuel pumps, electric cooling fans, starter motors, air horns, and HID or LED light bars. It is also suitable for controlling car audio systems, air compressors, and other aftermarket accessories in Cars, Trucks, Vans, Motorcycles, and Marine Boats. The standard 4-prong layout ensures compatibility with most generic relay harnesses and fuse blocks. PREMIUM BUILD QUALITY: Unlike cheap aluminum alternatives, the BLARYETI relay features a 100% Solid Pure Copper Coil and Silver Alloy Contacts. This construction ensures superior electrical conductivity, minimal resistance, and rapid magnetic activation. The durable composite shell is fire-retardant and sealed to withstand high engine bay temperatures, vibration, and moisture. Rated for over 100,000 switching cycles, this relay provides long-lasting reliability for professional mechanics and DIY enthusiasts. TECHNICAL SPECIFICATIONS: Model: JD1912 Coil Voltage: 12 Volts DC Current Rating: 40 Amps Contact Configuration: SPST (Single Pole Single Throw) Pin Count: 4 Pins (85, 86, 30, 87) Contact Type: Normally Open (NO) Terminal Material: Copper and Silver AlloyMAX 40A HIGH POWER: Heavy-duty 4-Pin SPST (Single Pole Single Throw) configuration handles DC 12V 40A loads reliablyUNIVERSAL COMPATIBILITY: Fits standard Relay Harnesses or can be wired directly using Female Crimp ConnectorsPURE COPPER COIL: Built with solid copper internals to sustain High Switching Capability without overheating (No Aluminum)PROTECTS ELECTRONICS: Safely powers LED Light Bars, Fans, and Horns by isolating high current from dashboard switchesDURABLE DESIGN: Engineered for harsh automotive environments with a lifespan of 100,000+ operations
