12V 24V Automotive Relay, 100A SPDT, 5-Pin 4-Pin, Waterproof, for Car and Marine High Current Switching (A3)

This 12V/24V automotive relay is a heavy-duty switching component designed to handle high current loads of up to 100A, making it ideal for demanding car, truck, and marine electrical applications. Available in both 5-pin and 4-pin configurations, the SPDT (Single Pole Double Throw) design offers versatile switching between two circuits through a common terminal, giving you greater flexibility when wiring accessories or control devices. The transparent housing allows for easy visual inspection of internal components, including the copper coil winding and the built-in green LED indicator that confirms when the relay is energized. Wide voltage compatibility supports both 12V and 24V DC electrical systems, making it suitable for a broad range of vehicles. The waterproof construction ensures reliable operation even in wet or harsh under-hood environments. Clearly labeled terminals (30, 85, 86, 87, 87a) simplify installation and wiring. Whether you're controlling high-draw accessories like winches, lighting, or cooling fans, this compact and durable relay delivers consistent, long-term performance in even the most demanding conditions.
