High-current switching for 12V systems: This 200A relay reliably handles heavy loads in 12V DC automotive electrical systems, allowing you to switch high-current circuits without overloading dashboard switches or wiring. Sealed construction for durability: The sealed housing protects internal contacts from moisture, dust, and road contaminants, improving longevity and consistent operation in vehicle environments. Easy, secure installation: Built-in fixing holes let you mount the relay quickly and firmly to a chassis or bracket, reducing vibration and ensuring stable connections in automotive applications. Clear compatibility and function: Designed for 12V DC automotive circuits, this relay is suitable wherever a high-current, single-relay solution is needed. You receive one high-quality relay in the package. Practical applications Auxiliary lighting and light bars: Use the relay to power aftermarket headlights or LED light bars, keeping high current off interior switches and reducing heat in switch circuits. Winches and high-current accessories: Ideal for winches, power inverters, and other accessories that draw large currents, providing safe switching and protection for control wiring. Cooling fans and pumps: Switch radiator fans, electric water pumps, or fuel pumps that require robust, repeatable high-current switching in automotive environments. What this solves Prevents damage to low-current switches and wiring by relocating high-current switching to the relay. Reduces risk of contact failure from environmental exposure thanks to the sealed construction. Simplifies mounting and wiring with integrated fixing holes for a secure installation. What’s included 1 piece of 200A, 12V DC sealed automotive relay with fixing holes.
